Hi guys, I'm a little confused on what my best course of action is with my setup. The car is a street rod and I originaly had a heads/cam 346 with a 98 computer and painless harness. I used LS1Edit to tune. Well this winter I changed the combo all around. I redid the engine lowering the compression and added twin 62mm turbos. I also purchased efilive V1 and repinned my harness to 99-02 config and installed a 02 computer.
Here are the car specs
346 9.5 - 1 compression
Dart 225 heads
80lb injectors
22x/23x .600" 114
twin precision 6265 62mm turbos
Th400 with transbrake and 4k stall converter

I'm only planning on running about 15 - 20psi. I'm guessing I should be using cos5. What should I do to get this thing fired up and start tuning? Should I add the cos first or wait till after I fire it up? Or should I try to find someone with a similar setup and use that as a base?

Thanks for any advise or guidance,
Frank

A starter tune from someone with a very similar setup is always nice. But, you could start off with a 2002 COS 3/5 and input your IFR and scale up the main VE table about 20% and the boosted VE about 35% (For Safety). Then tune with a W/B O2 from there.

Thanks a ton Jeff!! I just downloaded the tune that was on the computer. I bought it from Jesse at wait4me and it was supposed to have a 02 fbody calibration in it. I have to load an 02 fbody os in there before I can do a cos right? Anyone know where I can find an 02 OS. Mine currently is 12202088

Thanks,
Frank

Goto www.holdencrazy.com (http://www.holdencrazy.com) and see the 2002 Camaro 12212156 file with the same transmission as yours.

Ok, I loaded the 12212156 os for a 02 manual trans. Where do I actually get the cos5 from? When I click on the tab there is no cos's listed. Sorry for the rookie questions, I'll pick it up quick!

Thanks,
Frank

If you have the latest V7.5 software installed it comes with COS5...

In folder C:\Documents and Settings\Joe\My Documents\EFILive\V7.5\Bins\Custom OS see file 02020005.tun.

Copy this file to your usual Bins folder (i.e. so you edit the copy).


You will need to follow these instructions: showpost.php?p=67875&postcount=243 (http://forum.efilive.com/showpost.php?p=67875&postcount=243)

Don't use the "Upgrade OS" tab in the tune tool.

No worries, all questions are welcome...:cheers:

hmm, I don't feel so dumb now. I was trying to do it that way and I don't have that file in my cos folder. I checked my software rev and it 7.5.3 build 36. I tried to upgrade and it won't do anything. Tried seting up automatic updates also. I guess my next step is removing it and reloading the latest version??

Thanks,
Frank

Do you have FlashScan V1 or V2...?

If you have V1 then download/install V7.5 from the link below.

If you have V2 then download/install V7.5 and V8.1 from the link below, and update V2 firmware/bootblock (after first carefully reading the attached doc).

Succes! I uninstalled my old version and loaded the new. Got the cos5 loaded up and stock tune loaded into that.

I do have one question though. Do I have to go through all that bootloader upgrade stuff or can I just use what I have? I did get a funky error about incorrect calibration or something when I went to put my tune into the newly loaded cos.

thanks,
Frank

You have V1...

The bootloader stuff is for V2.

Do you have a screenshot of that...?

After the COS5 full flash, did you cal-only flash from a 12212156 file...?

Does that error message come up again each time you cal-only flash...?

Does the engine crank and start up...?

Id din't come up when I loaded the cos, but it came up when I loaded the cal only flash from the 12212156 os. It basically said my calibration was screwed up in my computer and that I could read it or flash a new one in. I just figured it was because I had the new cos in there with no calibration loaded yet.

I'll try another cal only flash and see if it does it again. If it does how do I get a screen shot of it? I know it something to do with printscreen, but I'm having a brain fart right now.

Choose either method: hosted (post #1) or attached (post #2, easier).

Engine is not up and running yet, so I didn't try


Is this the error message you saw...?

I did see that one but that's not it. The one that came up was after I hit the program pcm with current cal button, and after I checked pcm. It came up when I hit start, but after the other 2 normal warning boxes.

I'll try and flash this tune I'm playing with tomorrow and see if it does it again.

I did another cal only reflash and that message didn't come up again. Everything went smooth as silk.
I am still getting the out of range for 11 calibrations even though I went through the tutorial and changed them. Is this normal?

Set the out-of-range value to max-1 or min+1 (whichever is closer), save file, exit tool, restart tool, set those back to max, except leave A0012, A0013 at 511...

when you now exit/restart tool there will be no out of range values.

Be sure to disable TPS VE.
