Are you using the settings in my new thread on the OMNI 4 bar? What ROM are you using?

Ah! Didn't know you made a new thread. I'm using 96940011. In comparison to the jdmmap settings, I've noticed the only differences are in the "Map comparison" and "Map vs Maf". Did I miss anything else?

Also, I'd like to understand how this sensor works. For what reason does the map scaling voltage end at 3.63? Shouldn't it read upto 5 volts? Or is that because all units above 3.63 volts are supposed to be 255? Thanks.

I'll try these new settings tomorrow and hope for the best! Thanks a lot!

There's too much good info in this thread to just let it fade away...let's keep it up near the top now that Tephra's v7 SD patch is released.

Thanks for all the information in setting this up. I'm looking forward to being able to log boost soon.

Our store has been plagued by issues

If you would like to order these we stock them at all times and only need a PM to get the process rolling

thanks

Ok, I'm tuning the SD setup, and I've gotten my omni 4 bar map sensor scaled in on the Tephra v7 mod patch as close as I possibly can get to matching up with the stock maf values I logged the day before. Everything looks good as far as fuel table-wise, but I'm getting some stumbling due to both my LTFT Low and Mid being at -12.45% right now. What is the best way to bring them back in check to where I had them previously with the stock maf (at around the 2.2% mark for LTFT Low only)?
