I'll assume A0014 and I do believe it does. As far as I know, it basically takes place of the VE table when you are in the window you have setup.Quote:

Cheers mate! Will be interesting to see how hard it will be to actually populate a map of TPS vs. RPM etc.
how does the pcm know if you are spraying nitrous or just wot without nitrous?
By the nitrous input switch earthing the PCM inputQuote:

A bit like that except it is the same tune just accessing a few extra offset tables to account for the spray. more akin to power/economy switch on the transQuote:

Just two to start with.
One for the Aussies to replace 12225074.
One for the 2002 F&Y bodies to replace 12212156
If you are already running a custom O.S based on one of those O.S's then all existing tunes are compatible.
Same process as the others, Full flash the O.S #5 tune in, then flash the cals only from the existing tune you are running, then read it out and save as your new O.S #5 file and adjust the new tables / parameters.
Setup suggestions.
A0003 - Set to disable for now until the tutorial is done (or you are feeling brave).
N20 monitor is done via the same input as the Valet mode, once it is grounded then the two compensation tables become active, although, there is two parameters to stop those two tables even if the N20 is on.
Good luck, let us all know how you go.

Ooooh a new challenge. Just when I was satisfied (finally) with my tune.
Let the games begin :rockon:
Cool, so what was it.. set A0003 to enable.. hehe..
So, ringram... You installed it yet LOL
Will have within the next hour.. maybe not initially with A0003

Well Ive started playing :D
Just a few thoughts and comments. The bottom half is rough, Im sure due to stuff I need to turn off like DFCO etc.
But I was thinking that cracker and follower are going to mess with this new TPS/VE table as its based on TPS and RPM. Cracker adds airflow separately from TPS so will affect VE, as will follower. I know Tordne zero'd out his cracker and follower at one point for testing, so my guess is to dial this in nice we will have to do that as well as the usual dfco, lean cruise etc.
Id say you would also want to fix PE to throttle trigger only and stop MAP triggers, again for consistency.
So yeah lots of different stuff to mess with, will take a while to figure it all out.
Anyway on the upgrade process, straight forward custom OS install, with the nice point that OS3 cals drop straight in. You can just leave the tps/ve stuff out until you want the challenge. Looking forward to everyone else's comments.
My thoughts are unless you are running a REALLY big cam with no vac there is probably no point running the TPS VE unless it's just for the fun of learning.
Cheers,
Ross
I wish my cable didnt go out yesterdayI wanted to play with this os. So with this OS I wont need a nitrous controller at all? If I understand this right, I can flip a switch and that will change some settings allowing me to use nitrous better. Im guessing it will allow me to pull timing and richen the car up.
You still need a controller for the N20 solenoid(s), however, this allows you to alter spark and fuel without needing additional injectors when the N20 is on. It is by no means to replace some of the very sophisticated N20 control boxes out there. But for the guy with a small system who just needs to add a bit more fuel and pull a bit of timing it is ideal.
The other part of this O.S is the TPS mapped VE for big cam engines or trumpet style manifolds.
Cheers.
Ross
Agreed, its really for hardcore race cams. Just playing for something to do :)
I don't think the VE Lookup Table PID will be affected by Follower, Cracker etc. As I understand it it looks up the value from the standard VE table at the RPM vs. MAP point. Then because you are creating a MAP of RPM vs. TPS then that VE Lookup Table value will basically be placed in the appropriate cell. Therefore building your TPS VE table.
I started playing yesterday. It is quite evident that it will be pretty damn hard to populate that table on the road ;)
Ok, but say Im doing 100mph, cracker will be at a higher value than just on idle. Therefore at the same RPM and TPS Ill have more air going in with cracker so less vacuum, so the ve reading at that TPS and RPM point will be different for the 100mph condition as opposed to me just reving at idle for example. 2 different ve/map readings same tps and rpm.
Maybe its not going to make much difference a few extra grams wont do too much when you are near the top of the table. But at low points it could get a little messy Id have thought.
I know what you mean about populating the table though, especially all the throttle points over 5000rpm. I guess you can see the pattern and then fill it in by hand. Should be interesting to see what happens with AFR's running of the table.
I know where you are coming from Richard and I agree, but, for the engines that TPS VE will benefit the effect will be negligible.
However, as you guys are having so much fun, let us know what you find ?
Cheers,
Ross
Hmmm... sounds like too much fun, I'll have to give it a whirl... :)
I don't know if you need a big cam to take advantage of TPS vs VE Mult feature but I believe my baby cammed LS1 needs this table:
Case in point
My car bucks badly at around 1600rpm in 5th at cruise when constantly on and off the throttle at light inputs. I reduce the VE table b/w 1600-2000rpm by 2%. Bucking stops. But engine pings at moderate %TPS. I have to take a serious chunk of timing out (6*) between 1600-2000rpm to stop the pinging. No more bucking and no more pinging. However, the problem is that I've lost that effortless overtaking capability because I've lost timing. The only way I can restore the timing is to richen the mixture but then I'll re-introduce the dreaded bucking... which is why I badly need the TPS vs VE Mult table.
Can't wait to try it!
The one problem this does have is in an A4 transitioning in and out of Drive, there is no detected load change for the VE, however that also has an advantage too because the fueling remains constant and the spark / IAC handles the RPM drop.
I ran this in my car for about a month a while back, and given plenty of logging time for BEN factors you can get the AFR's so spot on you'd think the WBO2 was stuck!
Cheers,
Ross
SSB, check your base spark and high octane spark. If they are way different at the points you mention try closing the gap, seemed to help for me with a similar problem when hardly using throttle at low speed.
I'm now running on OS5 as well. Just cause I can really, more than really needing it :)
But I have a question.. Where is, or what is/was OS4? How did we arrive at 5?
And now onto mapping the TPS VE Table :)
Is there any guidance on what settings should be used for the RPM, MAP and TP exit points?
Cheers,
V4 was going to be the N20 options only, but in the end it was possible to squeeze everything in to one O.S, though, on the later 2004+ O.S's this might not be possible. There is a few cars in Aus running O.S #4, it's been out for a long time, but these were only used by workshops for N2O cars only.Quote:

Besides, nearly all 2003+ O.S' are used on ETC applications, I am not sure the TPS VE table would work too well on them.
Cheers,
Ross
Never mind, lets us old skool pcm and tb guys have one up on the jones's.
Bragging rights. :cheers:
So I have managed to map a reasonable portion of what will be the TPS VE Table. I have filled in the blanks and have basically got what I think is a reasonable first cut at this table.
So, the next test is to go and drive it. I have set all TPS VE Table disablers high, so that it will run exclusively from the TPS VE Table.
I have also made a MAP that will represent the BEN factor for the table to allow for correction (or at least that is the plan).
I'll probably give this a go in the next little while (gently :)) and then if all is looking OK might even drive it home like that :)
This is all very exciting :cheers:
I'll be online here in a bit to help you out on it. I would add a little to your TPS table that you have plotted to ensure it isn't lean. ;)Quote:

Ross, can you confirm/deny that the values in the TPS VE Table are multiplied by A0014 multiplier? I am finding that the values in the TPS table are higher than my regular VE :eek:
Cheers,
Yes that table is still used. i don't imagine the TPS VE table is going to look to similar to a MAP based one.
I guess everyone figured out you need to log the VE Table value PID to initially populate the TPS VE table.
Cheers,
Ross
Thanks mate :beer:
I just wanted to confirm cause the values are different than the MAP VE. I was expecting the shape etc. to be very different, but I figured that max value (Grams*Kelvin/kPa) would be the same in the MAP and TPS VE?
Yeah I logged the VE Lookup PID some time ago testing another theory. so this time I just made a MAP that looked like the TPS VE Table and the went for a drive (using the regular VE) to build the base table. Then I shaped it, filling in the messed areas, and the increased by a couple of % for error. Turned out to be pretty damn close in my case :)
Cheers,
I almost forgot, the VE look up PID only works when using it in K*, if you do it in a % it reports a 0. At least for me it does. I have been known to not know what to do sometimes.Quote:

High praise indeed :) I guess I must have too much time on my hands :muahaha:
Andrew, you got it down to a science :rockon:, when I get ready to do COS's I'll be asking you questions... hmmm... why don't I just come visit you... :D I should be about due for a long trip down under sometime in the mid future. :cheers:Quote:

Flash count is sitting on 892 right now. So each flash has cost me under US$1 now, just need to work on getting it down to NZ$1. So, another couple of hundred flashes required.
I've seen a couple of peoples FlashScan boxes go out. That would be my greatest nightmare LOL. Then I'd have to the to the wife j/k
At least living in the same city as Paul I could probably swing by and get another one :)
You should definitely give the COS a go, at least V3 with the RPM/MAP fuel table and dual spark maps.
