Cutting out in boost when warm only.

[akurtzer57]

Little backround on car. Vg30et, z32 maf, he351cw 18psi. Injector duty cycle 73%NGK 2 step colder gapped at .28 Car pulls amazing but once gets fully warmed up cuts out in boost. Drives normal when don't get on it. I got a datalog of it cutting out. Everything looks normal except ign timing running -12 in boost. AFR steady 11-11.7 I tried getting a log of it before got fully warmed up time got to highway was warm and cut out. I can load my bin and some logs will have to use my other computer to do so.

looks like you hit TP load limit (Load cut TP limit table). Doesn't?

I fixed the cutting out with new plugs. Still seeing negative timing under boost on all my datalogs. Car pulls well still don't understand why its showing negative timing. Always around -12 Anyone???

post the BIN file?

[akurtzer57]

Heres my bin file. Pulls smooth and nice power with this tune. Drivs great besides rich at speeds below 60-70 mph.

Okay will have a look tomorrow

I'm not throwing any codes but could my knock sensor or cas cause this.

[Matt]

Knock sensor will normally pull timing. You can disconnect it to test it out temporarily

CAS normally will fault code (DTC) and car stops working. Sorry I've been slack and not run your file in an ECU on the bench yet (have to program up everything to test it out and repeat the issue)
