2013 Mustang GT Auto RPM limit Problems

[rlw020987]

I am currently working on a 2013 Mustang GT with the 6R80. I cant seem to get it to rev past 6000rpm. I keep hitting some sort of limit. Would not readjusting the RPM axis in the torque management tables for the transmission cause the rpm to still be limited? I am running out of ideas why the car hits a limiter at 6000rpm.

Can anyone help me out here. I have tried everything yet I am still hitting a 6000 rpm limiter. Eric@Hptuners any suggestions?

Can you please post what mods you have made to your car? I have compared your tune to a stock 2013 Auto GT and there are significant multiple differences in your specific calibration. Tell us what you have done to the car... LTs, CAI, Blower? Once you provide some detail, I am sure that some of the senior tuners on the forum will jump right in.

2013 mustang GT, boss intake, boss exhaust cams, boss valve springs, on3 twin turbo kit, with off-road X-pipe, FIC 850cc injectors. The car hits a 6000rpm rev limiter no matter what. It will do it in 3rd, 4th, neutral and park. I have combed through every table with no ideas!

Shouldn't the cylair WOT multiplier and Cylair multi be higher for a boosted car?

I have a couple of other boosted tunes that I have been comparing mine to, It seems to be the same but I truly do not know.

[15PSI]

It is a good practice to set Cylair Max Multi and Cylair WOT Multi to 1.9 (or 1.99 like my mine) for a boosted car. Doesn't hurt for NA cars too. But I don't think this would set an artificial speed limit. What TB are you running? I will look at your calibration later today when I have time.

I just sent you a PM

[rlw020987]

I will fix the cylair numbers today. Any ideas why it would be hitting a rpm limiter?

Try maxing the Exhaust Temp Inverse table under Fuel -> COT.

Edit: Just saw you post that it does it in neutral, probably not Exhaust Temp but it should be raised a bit anyway.

One additional item, double check the FIC data for your injectors. I doubt this has an affect on your limit issue, but a lot of folks have had issues with the data provided by FIC (the reason many pay the big bucks for IDs, because of Pauls very good data provided with each set). Even though the injectors might not be dialed in, they can still have a negative affect on driveability etc etc...

I have tried maxing these out. I thought the same thing especially with a turbo kit

I have delt with FIC for years without issue. I am good with the injector data.

I did not know you can log each source. Thanks

I know the torque source keeps popping up rpm limit
