Tuning with fuel trims

[68problemchild]

Roger that.

I guess what I am trying to do is change a polynomial with a multiplier which is fine with me if it works. The above process will be for another day. Happy to take a run at it at a later time.

In the interim, I will be thrilled if I can get a ben map created to produce cut and pastable data with the LTFT's. I have them turned off now. I probably should turn them on, turn off STFT's (location?) and get this new ben map installed. Hopefully you all can help with that.

Looking at my file above its empty.

THanks!!!!!!!!!!!!!!!!!!!!!!

You should be able to turn on LTFT's quite easily. You don't need to 'do anything' to STFT's..in closed-loop they need to run. LTFT's are just a lot of STFT's averaged over time.

I have zero experience with your OS, so I hesitate to comment much. Having said that I thought almost as OS's came with a BEN Pid. Its the essence of Tuning. That file you 'attached' looked like an empty sae.generic file, not a calc_pids.txt file. What does your calc_pids.txt file look like?

Look in your computer here:My Documents\EFILive\V7.5\User Configuration\calc_pids.txt

Good luck..

That is my calc pids txt file in the location you described. I just cut and pasted the contents for simplicity.

So my file should not be blank?

Pat, where are you with this...?

[68problemchild]

Well I kind of dropped the ball since my O2 sensors came back. Now its back to trying to get them to work.

I dont have any experience with the E38, but I tuned two GTO's with the E40 last summer with the original version of CALC.VE worked awesome. Just obviously make the maps match the tables. I am curious about the E38, I might have to pull the tune on one and have a look.

The E38 is a totally different animal ... can't use traditional LS1 PCM style AutoVE or CALC.VE tuning techniques.

Hello all,

How do I make a Calc Pid for STFT's and LTFT's to convert it into a Ben map for a E38???

This is my Calc Pid file - calc_pids.txt

I went into the file but it may aswell be written in chinese


Cheers

Ben

Hello Ben,

Have you read through Swingtan's E38 VVE tuning tutorial ? It details tuning the VVE and MAF.
