Looking for some help with the v7 ROM. Still have yet to receive help for issues I have posted a month ago. Cannot get over 5000 RPM's with v7, whether it is the 94170715 or the 96530706 ROM. Previous tune works amazing on v5, but v5 does not have gear-based boost control...
I am seeming to hit a fuel cut of sorts, not a boost cut. Almost seems like the MAF sensor is reading incorrectly, though everything works fine in v5 (same values!). Attached is my v5 (evo7base.xml, 94170015.xml), v7 (94170715-v7 and 94170715-v7)XML and datalog (showing v5 and v7 operation). The datalog for v7 does not seem to be showing anything interesting as far as what the problem may be...
I had a problem years ago where my ECU wasn't getting a speed signal, so it kept hitting the stationary rev limit when driving.
I see you're getting speed in your logs though, so it's unlikely, but a simple test would be to increase your 'Stationary Rev Limiter (launch)' to 7000rpm and then test again. At least it might narrow it down.
Thank you for the responses. I will try changing stationary rev limit to 7000 real quick and try that, as well as disabling NLTS. It seems the injector pulse width duty cycle decreases to 4%, but never to zero. The 4% may be attributable to when I lift off the throttle, however.
So, per Tephra's suggest I just turned off NLTS. While I was at it I disabled everything else such as valet, alt maps, launch maps, etc. I also set my Launch RPM limit to 7500. I went an ran through 1st gear and this is what happend:
The car stalled at 2 instances, during these two instances the car registered 7 counts of knock. The car was able to move through these two stall instances, and I was able to get to 7000 RPM before I let off. On v5 the car would not knock during these loads / the tune is fine. This is attributable to this stalling phenomenon.
The datalog shows that during these stalling instances, the WGDC went to 10%. The option to drop boost on high knock was enabled, so this is likely attributable to that nice failsafe feature. The stalls I was encountering before were the same as this time as well. Normally when the car knocks the car is pulling through the RPM band as usual, but during these knock occurences it was happening during the stalling events.

Ideas?
Any help would be greatly appreciated!

Facing the same issue but with 9653 with MAF car stalls at 2500 RPM when i floor the throttle, afr goes lean into 17s almost like a 2 step but at gradual throttle it goes past 2500 rpm.

You're putting a huge load on the engine if you are flooring it at 2500 rpm. Just downshift and then floor it.

I understand this but i road tune cars , we dont have a dyno here. So i try to go through as many load zones as possible. This happens not only just flooring it but when i start it up and rev it , it wont go past 2500 rpm smoothly.... cuts n hangs.
Is there any FCA or FAA bits that might cause this ?
Solved the problem. At the same instant i was having 2 xmls for 96530706 1 was for evo 8 and the other was for evo 7 which was some how causing that problem. As soon as i removed the evo 7 XML from rommetadata evo folder the throttle hang on accel was gone.
Is it okay to not use the romdata / evo folder for .XML files? I use a completely separate folder for everything. One folder for v7 rom and xml, another for v5, another for stock, etc., not in the ecuflash directory. I always change the directories in ecuflash switching between the two. Could this be why I may be having issues somehow?
