so we have an 09 ctsv that has a 2.45 upper and i have addeed the log. the maf is stopping at 86.69lbm for some reason and i am seeing engine tq stop at 640 like i am hitting some load limit what did i miss. timing is safe at 20* and the pump is turned up to 600 kpa as well Attachment 101966Attachment 101967Attachment 101968
A quick look and it looks like you are getting a few mis fires....did you re-gap your spark plugs after installing the 2.45 pulley? and that is definitely weird how your maf just stops like that...
VE airflow stops at 512.0 g/s (67.73 lb/m), and MAF airflow stops at 655.4 g/s (86.69 lb/m) in the scanner. Dynamic Airflow keeps on going though. Log all three and you'll see it.
What mods have been done?
we found some of it got it back on the dyno an fuel pressure is not holding good its dropping out . didnt lean out on the dyno with less load to turn the drum put some load on it with the eddie brake and load goes nuts injector being to open to add more fuel to. we just have the a 2.45 and bre7ef ngk gap at 35
I have the same issue with e67 ecu but this is a swap engine, can you please tell me if you solve this issue.Quote:

i've noticed that as well that the maf stops at 655 g/sec...is that normal?Quote:

Its seems like the car breaking at wide open above 4000 rpm but the fuel shows around the target, also i notice the cylinder air mass goes too high, can you please let me know what PID's i am missing in data log so i can add them in my channels and do another pull

Thanks you very much and appreciated, let me try with this and let me check what exactly the cause.Quote:
