Hi all, im looking for the os to a 98 s-10. Im wanting to do a 411 pcm swap on one. Any help would be great :secret::cucumber:

Don't you need an OS from a 2001 vehicle?
Why do you need an OS from a 98 S-10? 4cyl? 6 cyl?
Here's one from a 6 cyl

[haulinit]

Maybe Im confused. Here is what I want to try and do. I want to swap a 411 in place of the 16228016 pcm, so I can tune it with my V1 cable. I dont really have the money to swap to a v2. The s-10 im wanting to do this to is a 98 s-10 with the 2.2L 4cyl. Can it be done?

[chevy052500hd]

no it can't be done 0411 pcm has not been installed on a 4cyl from gm so there is no os that will work with your setup.

Probably tooooo much thinking outside of the box, but, do we know if the 2.2L uses the same or similar speed timing wheels? If so, could he throw on a 0411 and just hook up 1/2 of the injectors and coils? Turn off the codes for the rest and the misfire stuff too? It's just 1/2 a V8 .... main key with this logic is IF a 2.2L has the right stuff to tell the ECM it's running.

[haulinit]

I forgot about this thread. When you say speed wheels do you mean the speed encoder wheel in the tranny? I think there would be other issues other then the OS, like the pin outs in the harness would be in different locations. I would have to repin the harness for the 411.

No - speed timing wheels on the crank (24X) and cam (1X). As long as you can show the 0411 valid speed signals, it will think it is running and thus you could try to make it work. Key being 1) does the 2.2L have a 24X crank and 1X cam speed wheels and 2) are the orientation of the speed wheels to the speed sensors the same (i.e. does the missing tooth on the crank wheel line up with say #1 TDC in the 2.2L like it does in a 5.7L???? I totally made this condition up, but you get the idea. They need to be the same or at least very close).

Hi this is my first post and I dont mean to hijack, but I also have a 98 S10 with the 2.2. I have a turbo on mine and have never been able to tune it for boost. So im forced to use an fmu with 24lb injectors, stock is 19lbs I think. I just threw the 24pounders in and it runs ok for no tune. But the ecm is always tryin to pull fuel, not a real lot but enough. I know im leavin alot on the table.Its frustrating. Turbo bu, great thinking im going to try to find the info on the speed timing wheels. Do you think this could really work if they are the same or close? This forum is great ive read so much on here in the last month. Those guys are great in the vortec forum on this site. they are always lookin for people to help out. Sorry for the long post.

[slows10]

Ive got some info. On the crank wheel there are 7 slots, each spaced 60 degrees apart and the 7th slot is spaced 10 degrees from one slot to serve as a syncronizing mark for TDC. Im looking for cam wheel info. But not looking good to work.

[ScarabEpic22]

So you have a 7x crank reluctor? The 02-05 4.2L I6 motors do as well, but dont use their PCM as its basically a 4cyl PCM modded to run 6 cylinders and exhaust cam VVT. Id recommend using an 04-06 P12 PCM, run a Colorado I4 OS. At least then you can manipulate the tuning easier than with a 4cyl PCM. You have to use a V2 to tune them however.

slows10 - since it sounds like the speed timing wheels are noticable different (it would take considerable effort to get something to work), I was wondering if you had ever thought of doing a 2 bar MAP sensor hack on your existing ECM. From my reading / experience on LT1's (early flash PCM's), there never were any COS's for making them boosted. The work around that guys did was to throw in a 2 bar map sensor and scale everything else to make it work. Yes, very HACK, but effective none the less. This way you could still use EFILive to make changes to your tune and not have to monkey with FMU's.

[slows10]

Hi turbo bu , yes I have thought of doing the 2 bar setup a few times. Ive looked at different threads on some other forums and it seems like I could never really tell if it worked well for the guys that tried it. seems like people start the threads and never report back how they made out. So for instance on this setup 100 kpa would now be 50 kpa 80 to 40 etc.?Would the driveability suffer a bit with the tables split? So you have seen this work pretty well? I really would rather stay with the stock pcm so I dont have to rewire and all that. Im going to search a little more for a few decent threads that talk about it a little more. Thanks

[slows10]

And also scarabepic your saying that the 04-06 p12pcm and the colorado I4 os would have better tables and more tuning parameters than my lame ecm has? If it does than maybe try the 2 bar map hack on that pcm. Might work out good. thanks P.S maybe start a new thread or is this one ok ?

Yes thats exactly what Im saying. I assume the firing order is the same, only thing would be the VVT stuff (Colorado I4 has it, dont think you do).

Unfortunately the P12 doesnt have a ton of available params, only the basics to get a mild tune done. You could probably 2Bar it and have a little better control simply because its a newer PCM with more resolution in each spark table.

[slows10]

Where can I go besides paying at alldata to find wiring pinouts on a couple of different year s10 trucks? Is there a general website or something that has this info? thanks, Keith

[nevinsb]

Man, I wish I was back at home, but the next time I take leave will be around the end of year holidays. I have all the GM diagrams for up to 2007, but you could ask on s10planet. Make sure you note that King_Ice_Flash sent you, and be sure to send some pics.

Yes, what you have said is what happens. All the MAP based tables basically get cut in half. You do give up some resolution, but what you gain back is the ability to control fuel and spark in the boosted section of your operating range. For setups that are not fully supported (like LT1's and your S10), this is a viable option which works. If your still interested, I can give you some of the basics.

[slows10]

yes very interested!! But let me give you my whole story in a nutshell. My brother and I both have s10's. Mine is the 98 2.2 5spd. His is a 1997 4.3 v6 vortec with the black box pcm. As you know mine is boosted. We are currently putting a turbo setup on his. So we have been looking for tuning solutions to both our trucks. For the past few months I have been looking at the other forum for solutions and info, but in all honesty I did not care for that forum and the way peoples questions were answered, they just did not do anything for me. So one day I was doing some searching and came across efi live and went to the vortec forum here and was really suprised at all the info that was here and the way people were helping each other. Then I clicked on lextech's thread about the 411 pcm conversion for the black box ecm. That did it for me because now we may have a solution to my brothers 4.3 tuning boost situation. Now I dont even have efi live yet but we are going to order it shortly.Im sure with some help from you guys we can get my 2.2 ecm workin for boost.Im going to post in the vortec forum soon. Now im no computer expert, im the mechanical guy. I know what an engine needs for fuel, timing etc. My brother is the computer whiz but lacks in the engine theory part of it.So together we can probably have alot of fun with our trucks and efi live. So maybe in a week or two when we get efi live you can go over some of the things I need to do for boost tuning. In the meantime I need to find some pinouts for my brthers truck and the 411 pcm. Ive got some other questions also but ill add them later tonight. Thanks alot for the help turbo bu. sorry for the long post but I wanted my situation told up front. Thanks Keith

What about the cobalt supercharged pcm 05-07? Anyone know what reluctor wheel setup they have? Ive looked for about a half hour and cant find that info.

Scarab,

Do you happen to have copy of a P12 tune? I opened up a copy of my '99 2.2L tune and realized that it also appears to not be too boost friendly from the fueling side of things. The fuel maps are load vs. RPM and not kPa vs. RPM (think this is the similar downfall of the P10 PCM's). Hopefully, the P12's use MAP.

[slows10]

Yep the pcm im using which also came in the cavaliers as well as S10's are alpha-n setup. Rpm x Tps. So you really cant split the map table correct? Maybe the fake 2 bar setups ive read about were for another pcm and I got mixed up. But anyway is it possible to tune of the last map column? I mean after 105 kpa .maybe stick some numbers in there as the rpm goes up? Maybe the older cobalt ecm with the supercharger setup will work. Or I think chevy offered the supercharger setup on like 02 cavaliers with the LD9 engine as a kit. Thanks for the help

[ScarabEpic22]

They use the P12 PCM Im talking about with a Cobalt SS/Ion Redline specific OS and Cal. Should be a 7x reluctor wheel.

I have a few 06 4.2L I6 P12 tunes, no I4 Colorados I think. I might have 1 I5 Coly file, but they're on my external HDD (which I happened to leave in Spokane this week, be back there on friday).

This is exactly the problem, the VE table of the P10 is RPM vs Load % and spark tables are RPM vs MAP. Spark was easy to dial in, I still cant figure out the VE perfectly as the Load % PID EFILive has is worthless and gives bogus data.

You could split the spark tables quite easily using a 2Bar MAP, but the side effect will be what happens to fueling?



For anyone considering using the 06 Cobalt SS s/c OS and cal, be warned it is for manuals only. There are no tables related to an auto trans in the OS period (from what some people and a few HPT guys have said). So if you have an auto and want to keep it, look at a Colorado I4 instead.

[slows10]

Erik before I get confused anymore lol, what do you think I should run. What do I need? First do I need to find the pinouts on the P12 pcm, then purchase a P12 pcm, then do I need to find someone who has a cobalt supercharged file? Thanks keith.

[slows10]

Forgive me if I ask stupid questions. Just a newb to all this pcm swapping, but I think I can get it.

I think a P12 PCM should work well for you. I have the pinouts for a P12 used in a TrailBlazer so they wont be of any use for you. Once you have the pinouts, buy the PCM connectors and swap the wires from your original PCM to the P12. Then buy a P12 (any 04-06 one will work, not an 07), get a 06 Cobalt SS S/C file and FULL flash it in your PCM. Make sure it runs, then start tuning.

Disclaimer: I dont know if this will work or not, Ive heard conflicting reports even within the TrailBlazer platform that GM switched BCMs and they use a different communication protocol than the older ones. So even if all the wiring matches up, I dont know if the BCM you have in your car will accept the P12 comm protocol.

[turbo_bu]

Not really trying to make it any more confusing, but do we know what the reluctor wheel is for the old vortec (thinking like 1998 truck engines) setup? Thinking back to an option that would avoid all the BCM issues (or non-issues if this works). I did look at a copy of a '98 K1500 with a 350 .... it has both fuel and spark that are MAP vs. RPM.

Key would be that these engines have the 7X reluctor wheel setup.

[Lextech]

The GMT400 trucks (96-2000) trucks and the 01-02 Express Vans with the 5.0 and 5.7 distributored engines use a 4x reluctor.

Honestly if you could get the black box PCM to work you should do an 0411 LS1 PCM swap then run an Express Van OS. But since they use a 4x reluctor, no dice. Plus its a V8 vs I4.

Im going to hold out hope that the P12 + I4 motor + Cobalt SS S/C OS/Cal is the ticket.

[slows10]

Im going to look for info on the 2.4 Ld9 engine that came in the cavaliers. I think GM offered the supercharger in kit form for these engines and you had to bring your car to the dealer to have the pcm reflashed for boost. Not sure if the Ld9 has a 7x reluctor or not. If this doesnt work, then Erik's suggestion will work provided the bcm in my truck will work with the p12 pcm. Erik, is the only way to find this out is to actually do the swap and see if it works or not? thanks Keith

[slows10]

whoops I was postin while you were.

[ScarabEpic22]

Keith, I think so unfortunately. I dont have access to any of the cars you guys are talking about, Im just dumping the information Ive learned over the years. If the P12 works with your BCM, then the last thing will be to figure out what to do with the P12s exhaust cam VVT settings. Your motor wont have the sensor or ability to control it, maybe do some digging in the PCM to see if we can shut it off.

[slows10]

Ok not a problem if it doesnt work. I dont think its real expensive to do this swap and if it does not work oh well. I will have learned some stuff.

[slows10]

Got to order efilive pretty quick anyway. Im going to need the v2 correct?

[ScarabEpic22]

To touch a 4Cyl PCM I believe you need a V2. For a P12 you have to have a V2 as it communicates via CAN which V1 cant communicate on.

[slows10]

ive got some info. apparently I can flash a Ld9 s/c tune to my s10 pcm. The ld9 shares the same 7x reluctor as my pcm. Im not sure if this reflash installs just the fuel and spark tables or the whole operating system from the ld9?? The same person told me if this flash does take on my s10(he is not 100% positive it will) that I might lose my gauge functions like the 99 earlier cavaliers do, conflict with the bcm. On 2000 and later cavaliers the reflash works and you dont lose gauge functions. So it works on cavaliers but nobody is sure if it will work on a s10, and who knows if the bcm will function with the new reflash. Anyway if it worked I would have 2 bar tuning. I guess only one way to find out. Anyone have any input on this? Thanks keith

[slows10]

new info. I just read that the ld9 s/c reflash will just change like one table in my pcm. Instead of the V/E table read as TPS it will read in KPA for the map. That is the only table its supposed to change. So it changes fueling from alpha-n to speed density.

Then you could split the table using a 2Bar MAP and be good, albeit with lower table resolution. Try it out!

Were you able to get your hands on a LD9 file? If you don't mind, please post it.

Turbo bu, I havent found one yet. Ive been getting all the info and supplies ready for my brothers 411 pcm swap in his s10. We should be getting it delivered by next thurs or friday. I will find the ld9 s/c reflash tune and post it as soon as I get it. Keith
