MAF Scaling for OFT F00C US/MT 2016
 

Since I can't data log using MAFv or IAM, is it possible for me to adjust MAF Scaling with the other parameters like AFR, LTFT, etc...? I recently installed a Perrin 3" intake with my setup as shown below and it obviously needs to be scaled.

hmmm its going to be painfull without maf V working. If you know someone with ecutek cable or brzedit they could log it for you

How painful? LOL! I do know someone with an ecutek cable. I can do CL/OL all in 1 log correct? I'm going to use VGI...


+1 for ecutek


C'mon @shiv I'm rooting for you!

The link above is my data log for a few 3rd gear pulls at WOT and a 2-3 pull at WOT. Since I can't log my mafV or IAM, can you tell me if my car is safe enough to run on my setup or should I replace my Perrin 3" and go back to my stock air box. Seems to me that I'm running a little lean, but my LTFT even at CL never dips below -10%

For some reason, RomRaider keeps freezing every time I try to download my Close Loop data log.

Yes its running quite lean your CL target afr is 12.4 and your afr is 13.8.

I would not run with that setup without rescaling maf

or putting stock intake back on

Can I rescale with the datalog information I have?

Your best option is to use the stock intake, and use a maf scale that works without modification. Don't believe everything vendors tell you. You will go in circles for months scaling an intake with a large diameter maf housing.

Thanks @steve99 and @Wayno

Reinstalled my stock airbox (k&n drop in), modded my air duct and have a Perrin inlet hose. Reflashed to OFT Stage 2 UEL E85. Below are datalogs for CL and 2 OL runs after some light driving. What do y'all think? @steve99 @Wayno

cannot tell too much from that log as its all light throttle.

fuel trims look ok

need a couple of full throttle runs

@steve99 you'd have to change my log. The first is my closed loop run. OL2.csv and OL3.csv is my open loop wot run on 3rd gear. I attached all 3 datalogs under that one link. Sorry, shoulda mentioned that.

Yep looks ok for an off the shelf tune on E85
