Again- BIG Thanks!!

Blind- thank you for the reply, much appreciated.

We found a source of information (paid video) that had explained that the early GM computers could not read injector values over 8.0 g/s and that...

UPDATE-

A friend of mine was able to help me get this beast going!

It took failing MAF (as many here recommended- THANK YOU!), scaling injectors & airflow tables by 50%. Now the fun of working...

Thank you for the reply! At this point I will try anything!!!

Could you recommend a start point for the Bias table?

Here is my latest attempt.

Again- will start and rev up at times (1-2 seconds) but never keeping running.

The more I increase flow rate vs KPA values the amount of run of time is reduced. This...

There is not a good reason- looking at my original NA tune and stock flex fuel tune these values do not match. I will adjust values back to stock Flex tune values.

Again, I thank you for the...

I will try the MAF fail and report back.

Inj Bank Select-

I took pieces of my NA tune from 0411 pcm and added to this OS for the P59 as a start point.
I am a beginner at best here but trying...

Huge thanks on the KPAvsFlow rate- i set values at LB/HR and the suppled chart from FIC was in G/S. the fine details on this have bit...

Hello-

Looking for start up Tune help. I attached my tune file and a start up log- not much to see but maybe somebody can help. Truck will crank and somewhat sputter almost run for 1-3 seconds...

That's the difference!!! I was looking at a *C chart- MUCH APPERCIATED!!!

Thank you for confirming!! I tried using the LS3 MAF IAT scale but my reading was 20+ degrees low. Since I will be using the LSA IAT in the lid I will load the LS1 IAT calibration and see if this...

I am running P59 computer on LSA blower swap with ZL1 IAT in lid- Do I use the stock LS1/LS6 curve for IAT? I tired the above axis for the LS3 MAF card and reading was about 12 degrees low.

Did you ever get this figured out?? I am doing the same thing. 2000 GMC Sierra, LSA blower, P59 PCM and ZL1 IAT in lid. I have read with the ZL1 sensor the stock Ls1/Ls6 IAT curve will work, but I...
