question on custom os 0202005

[AllOutPerformance]

i converted a 2000 pickup to a 2156 os and it runs fine.I load the 0202005 for nitrous control and the truck starts and dies and wont run.
Ive done many custom os with great results.What am i missing.I full flashed the 2156 os then full flash the custom os then cal flash the 2156 in and the pull back out save as and re cal flash and it wont run.

Did it run properly on 12212156...?

When you cal only flashed from 12212156 was it the right 12212156 file...?

Did you disable A0003...?

Did you fix the out of range cells...?

Will it start but not run...?

Nate,

Look at B3647, it needs to be filled with good values.

Edit: he called me back, this is what we concluded.

Ok new problem
When converting from the 2000 O.S system 09354896 to 2156 01 and up O.S and ten adding the 02020005 custom os i have no timing retard when grounding red pin 56.Is it the early ecu that doesnt have the capacity to do this.Ive gone threw all tables with Joecar and we are at a loss.My next question is i have a 411 ecu i can toss in right now but do i have to eat a lic fee as i ave already lic the ecu that was in the truck.Thanks guys.

Nate, I pm'd Tech Support.


Make sure that you have it wired to pin 56 of connector J2 (it may not necessarily be red);

what year/model/vehicle is the original PCM...?

[Taz]

LS1-B PCM service numbers 09354896 and 12200411 are generally interchangeable - at least with OEM tunes. I believe that connector C2 (red) or C2 (green) pin 56 was never used in Gen III OEM tunes. Not sure about COS requirements - but if OS 12212156 was functional in that PCM - then logically the COS based on that OS should also function.

Don't want to see you use up a tuning licence unnecessarily. Sorry - I don't have an exact answer on this one.

Taz
