Where is the timing going?

[coanan]

Think this was the run on dyno.

[coanan]

This is the one he made a change to fuel mass. Said it was going lean up top.

The dyno run was suppose to be a boost and belt check and turned into this.

[coanan]

Could I have a bad MAP sensor??

This one is in it now, 53010887AA

HHP *Currently, we are waiting to confirm 100% that this is a 3 bar map sensor.

[coanan]

I'm guessing this tune has the best stumped?

Maybe this PCM is garbage to?

[coanan]

Just had a quick look at you log are there are a few weird things going on:
As soon as you hit a PR of 2.00 the driver demanded torque plummets but the actual TB stays open. Then for some reason the injector PW drops out big time.
Then it recovers and the vicious cycle repeats over. Its happening at only ~3800rpm in this log.

Do you have the actual tune file from this dyno run/log?

So, long story short. PCM doesn't know what to do over 2-bar. MAP setting in Eng diag. has to stay at 195kpa.

I remember reading about this years ago and forgot it.

Changed this and all worked out, no more breaking up. Will not see full MAP reading and boost in log, gauge read 15.3 psi boost.

[coanan]

So Pratio in log shows 1.92, boost shows 13.68 gauge shows 15.3

(14.7+13.68)/14.7 = 1.927 Gauge is wrong?? All I’m getting is 13.68 lbs of boost??

If so, that’s pretty weak for that eng and SC. Waisted money if that’s all I’m getting.

3 more lbs of boost over the little 2300 E-Force

Something has to be wrong.

Is the eng being held back because of the Max 195kpa?

Is the eng breathing soo good that boost is low?

Guess I need to get back on dyno and see where HP and torque numbers are.

[coanan]

So going by the one dyno log "with Max MAP in eng diag. set to 250kpa" PR made it to 1.99.

Intake volume was set at 16.50 also.

Doing math with PR 1.99 would make boost 15psi?

Is there a way to trick PCM so it doesn't freak out when setting is above 195kpa?

found this old thread that I forgot about. reading through it now.

More, need a work around.

shoot me your current tune and I will take a look. [email protected]

found this on HHPs site. only applies to the 5.7????

A question.

drive 2014 Chrysler 300c 5.7 AWD and swap the 5.7 intake manifold off and running 6.1 intake Manifold will this fit?

their answer

4 months ago
This will fit the 6.1L intake perfectly fine, you will just use 1 bolt instead of two to secure it. It may be overkill since there is a factory boost limitation in the VVT 5.7L preventing the PCM from reading past 2.0 bar so the extra boost capability is unusable - i.e. the 2 bar map sensor also works fine.

So. Do I revin a 11-14 6.4 SRT PCM?
