Guys I have an Ls swap vehicle with a 4.8, turbo cam 22/227, 80mm turbo, 210 bosch iunjectors from fuel injector connection, e85, Its on open loop Speed Density, Ls9 map sensor. I been having problems tuning it I have like sputter out of no where and my reading on the map graph starts at 85-95 kpa start driving and normal and goes up to 145. Heres the log and the file.
I was messing with timing tables that's why I left it all weird.
Its on 3 bar with the ls9 map sensor (red one)
You have the wrong MAP data in the tune.
LS9 or ZR1/ZL1 sensor like that is suppose to be 312.50 and -11.25 for the settings.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I swap the data and help more.
With the key forward my scanner graph jumps form 15kpa to 100kpa on 0.4 row. It?s that the way the map sensor reads with key forward?
I cannot upload a pic I?m on my phone.
