reduced engine power help

[nitrouspaul]

I converted to a 2 bar enhanced and am currently logging to get my ve right. My easy driving is good but tonight coming back from Kelseys I leaned into it a bit and it was pulling good when all of a sudden it fell flat on its face and went into reduced power mode. I had to drive home 5 miles like that. I restart it it is still in reduced power mode. Can someone look here and tell me why ??

thanks in advance

Also don't forget to raise the Maximum Delta Airflow-PO101 Error.

P0101 isnt that maf error code? what about the P0106 chart? do i touch that?

For the record, you can pull DTC's from the DIC and reset the PCM codes while driving and it'll take you out of REP. You don't have to limp home with it that way.

Really? That's awesome wished I has known car could barely make it up my country roads hills

I increased my 1514 table to 2.02 from 1.27 and will see what happens I am looking for a configuration file to plot cylinder air so I can see what it is actual rather than guess

Max out the table.

Max out the table.

Ah no, that goes against the advise of greg banish in another topic

No need to max it out. It is a fail safe to prevent a runaway train effect with your throttle body. Yes there are other fail safe items to help but if I were to give that type of advice, I would at least tell them the risk of having the throttle stick open and the car not go into REP and cause possible injury or death. At least then it's their decision.

All you need to do is make a histogram plotting cylinder airflow against the Calculated airmass vs. TPS vs RPM table and select max values over the default average. Then make sure you've got some headroom above that.

I have been running my cars like that since 2008 with table max out with no issue.

[nitrouspaul]

ok new problem went for a rip with the new settings and now my afr is stuck at .85 lambda rich at idel or low throttle positions whats that all about?

Because you havent had a throttle failure yet....don't max table (or other diagnostic protection tables) as advised above. Set it with the above instructions and add a 10-15% buffer....youll be glad you did if and when a failure ocurrs.

You can also turn off the vehicle, turn on x3 times to get out of REP.
