First suggestion, post the tune and log.
Sounds like you have a bad knock sensor or bad knock sensor harness.
If its popping and banging out the exhaust, look into your coils, coil harness, check spark plugs for micro cracks in the ceramic, or plug wires.
If its popping through the intake, she lean and...
The issue seems mechanical. Almost as if there is a coil or two not firing. Or, that popping you're hearing is a "lean pop" through the intake because of the MAF not being failed correctly. However,...
I've never seen much of a gain on 5.7s after 24 degrees on E85.
Did you check for power and ground at the CKP connector?
The fix is in the injector data
And this is why rookies come in here and get nothing but crickets. The forum didn't create the drama btw.
SOunds like your upstream o2 sensors are upset. Make sure your upstream o2s are reading correctly and not dumping fuel to one of the banks unnecessary
OP, you might wanna listen and try what they are offering.
I am in no way defending this tune. Could it be better? Of course. Any seasoned tuner would agree. I'm just not into slamming other tuners for their product.
I agree with edcmatt, way too high of an idle for that cam. I would typically set that combo to 800-825 RPM.
I just took a quick look. Tune doesn't look bad IMO. I always give vehicles that I tune a quick check up on the road after the dyno, before I call it good. I can't stand it when idle dips low when...
No reflash should be needed. Just swap sensors and HPFP over, and she should fire right up and be happy.
It should run okay with those mods and a stock calibration. Something else is up. Please elaborate on the situation with this car. Was it demodded? Was it bought at an auction? Etc
I've seen minimum spark set to full ignition timing in some tunes i've opened. Yikes.
You may also want to revisit your minimum spark table. Not enough negative spark in those tables, which is contributing to a very slow return to idle.
I will give you a hint, the fix is in your throttle map. Hope this helps
Unplug the battery for 5 min. Then try again. Should write normally after that
Segment swaps are the way to go, this way even VT and VVE gets easily emulated
Im sure if you post the tune, someone might help and send you a bare minimum tune to get the truck running.
Trust me, just do an L83 or L86 swap and segment swap the PCM. You'll be thankful you did.
Load this up. The 06-07 E38 for whatever reason hates the wheel hop TQ management and almost always interferes once the car is modified. I felt bad, so I also added a better timing table for you to...
Look at map points used on the S197, and tune it like you would tune a GEN 1 Coyote
What type of supercharger? That makes a huge difference.
