Help with understanding alignment of 4x cam and 58x crank reluctor wheels and sensor

That's awesome. Some serious progress in the past couple days! Glad to hear, sorry I can't offer any help. I'm tagging along for the learning experience! Great job David.

Also I was playing around with upgrading my TBSS OS to the EFILive Ethanol Custom OS and guess what, the LL8 shares the SAME OS!! So that means just like the V8s the I6 can now be setup to have a completely separate fuel IFR, spark tables, etc!

Besides the personal satisfaction "because I can" - this is another contributing factor why I am doing this! Very cool

Did you clear the codes in the PCM??? Oh, I know what happened.... EFI Live will not flash the throttle portion of the PCM, you have to take it to someone with a Tech 2 or some sort of J2534 flash device and have them flash it. You can change the ETC tables, but you cannot flash a new cal into a a E38 or E67 PCM and have the electronic throttle work. Sucks, but I assume they do that for safety concerns!!! If you need it flashed, I will do it for $65 w/shipping back to you.
Hope this helps!

Booo!! lol... not the answer I was looking for. If I can't get it figured out in the next couple of days - I'll take you up on your offer... thanks!

What about G1208, probably should be set to Disabled. And shouldnt you leave G1213 set to Yes? Or are you not wiring a clutch input to the ECM?

Can you post the bone stock file, I think the VATS needs to be set closer to stock params.

Your guess is as good as mine - I'll try those settings on my next go around... The stock file is the same one that's floating around here - if you cant find it, i'll send it to you when I get home. Thanks!

Nothing major to report at this time. Working some MAP/MAF correlation DTCs. I have a feeling it may be related to my ETC issues. Still no pedal response.

She still fires right up, sounds very strong for about 2 seconds and then kinda limps along on 1-2 cyls and then dies. I think its stupid rich right now. Injectors are not dead on, but they are pretty close for the scaling. Cyl volume has been adjusted to .5 but the VE tables have not been touched.

I'm still running on an engine stand without O2s and MAF so thats probably not helping...

MAP readings seem to be pretty high.. I'm seeing ~85kpa @ 1500rpm - 102kpa key off (I'm at sea level). Thoughts on that?

Thanks all!

Did your PCM come out of a LL8 Trailblazer initially? If not, it needs a full reflash with a Tech2 or J2534 compliant reflash device to get the ETC tables to work.... I will bet money on it.... Been there, done that. Even with Map/Maf corolation (sp) codes, the ETC should still work upon initial fire up!!! Refer to this post and it will explain what I am saying http://forum.efilive.com/showthread....l=1#post141633 look at post#5. That should clear up any confusion!!
Hope this helps!!!

Thanks for the info - I'm pretty convinced that's my problem. If I roll back to the original OS - the APP/ETC works again. Is there anything in addition to having the GM base tune written? Do i need to match up a certain pedal? Or will my current one work...?

Thanks!

Ive been told that only LL8 pedals work with the LL8 OS, but I could be wrong. Dont know about the I4/I5 pedals, they might work.

You just need to have the PCM flashed with the LL8 calibration with a Tech 2 or someone with a J2534 Compliant flash device. I flashed mine with our software and pulled the cal out of it and modified that one!
Just go on ebay and grab a VIN for the car that has the right motor and have someone flash it to that VIN, they just have to have an off board programming harness, or just make your own.

I tried using a gas pedal out of a HHR and it did not work, APPS2 had some wierd voltage curve going on, not even close to what the LL8 cal was expecting. You could tie the APPS 1 and 2 wires together and it would have the same voltage to PCM, but you would lose the failsafe feature that GM designed in. I used the Trailblazer gas pedal, wired it as a V8 and have had no problems with my test bench!!
