when deleting the AFM/DOD you have to change out the AFM camshaft. the lobes on the 4 AFM cylinders are different and if you retain the AFM cam while deleting the rest of the AFM/DOD system you will...

Your thread was a huge help. I was helping a buddy with his LY5 5.3 swapped 67 C10 using the E38. His fans would run all the time, after finding your thread I checked DTCs and had the same P0532 A/C...

thank you, it?s much appreciated. I?ll give it a look and work up from there. I just found out that the ECM and motor he?s using came from different donor vehicles so it will be good to checkout your...

I had him go double check it, the fuel pressure is at 55psi with it running. hes gone over it twice for vacuum leaks with negative results, that was my initial thought also.

Hello all,

I'm helping a buddy with his truck. We swapped an 07 LY5 5.3/4L60E and E38 ECM into his 68 Chevy truck. The motor was originally dod so all that was removed and a stock LS1 cam from an...

So, then I should try to check........?

I dont have on-star but i pulled the radio fuse and made sure headlights, dome lights etc were off. still nothing.
I was able to scan the other day when i tried but it wont let me read the VCM
...

I tried that once, let me hook it up and try again


Edit, tried again this time high speed read off. still saying ".4 preparing VCM -- failed " at the bottom it also says "boot loader download...

Im pretty sure its the MPVI, I bought the data logging pro version-2.22 last october to use for my '01 LS1 camaro. now i bought the DMAX truck and wanted to see if it would also work.

OK, I've been trying to read the VCM but it wont let me, it gets to the "preparing VCM" button then says failed. what could this be from? maybe it already has a tune from EFI live or a hand held???...

its an LB7. So I need to to nothing more then hook up the cables and start tuning? nice

Hello,

I have a the pro version of HPT for my '01 LS1 F-body. Today I bought an '04 Chevy Duramax is there a way to use what I have with the truck as well? or at least buy just the diesel program...

I will go back and reread but i believe he did it for safety?

Thanks, I knew it had to be something simple I was over looking.
I also found Russ K's IDLE config so i think i'll use it. im sure its better then the one I threw together lol.

back to my issues...

ok im going crazy, I actually had a little melt down earlier but im starting to recover LOL. spending so much on tuning software and equipment and not being able to use it or comfortably drive my car...

You two guys are great, I can't thank you enough.

your suggestion to add 10% was awesome, I added the 10% to the VE at idle and now its pretty close to right on with commanded AFR. I closed the TB...

Thanks a lot, I appreciate the insite.
I'll get on that and see how it goes. :drivin:

Thank you, after yesterdays issues I let it cool down, adjusted the throttle blade set screw a tad more, modifided the lid base to allow more air in. and what do you know, using your tune it started...

I cant open open the file for some reason??? it says "Unable to open file, Index was outside the bounds of the array" whatever that means?

Thanks a lot, Im actually on my way out the door for work, but i will try it first thing when i get home in the morning. :usa:

OK, so I played with the misfire diag tables and adjusted both idle tables and now my Misfire codes are gone.
I also did some reading on the TPS codes and found a post on LS1tech, I adjusted my...

well, as I bought the car with the enhanced OS already on it i dont have my stock OS either lol. I guess pulling a stock tune/OS out of the repository is out of the question?

so then i guess switching back to a different OS is not an easy task? Im on the 1 Bar SD OS, it was already on the car when I bought it.

Thanks for the help, is the only differance with the 1 bar SD OS that it has a VE multiplier vs. RPM vs. TSP table? mines set to 1.00 across the board so i guess its not being used either. I guess i...

I read where a long duration high lift cam can throw a misfire code and that changes to misfire diagnostic tables often need to be made. from driving and listening to the car I have yet to noticed...
