| I spent yesterday debugging this issue (see previous post previous post) And I am still unsure what is going on. Since the problem showed up after I added the Selin dual MAF translator, I started there. I reinstalled the single MAF setup and the problem appeared to go away. At least I do not feel any flat spot. So I tried the the second MAF in the single config and Ah Ha! the flat spot returned. At this point I am excited and relieved. I just need a new MAF. As a sanity check I decided to datalog the MAF, TPS, and A/F ratio. I started with the suspect MAF and sure enough
I can see where the A/F goes lean at 2400-2600rpm but in looking at the MAF signal it doesn't seem to be non linear. It actually looks about like I think it should. So I logged the good MAF. Now I am really confused. The good MAF data looks VERY similar to the suspect MAF. In fact
it shows a similar lean condition at the 2400-2600 range but I do not feel the flat spot with it installed. So now I am back to where I started. I have no idea if it is a MAF issue or something else like the TPS. Anyone better at deciphering logged data than I am is welcome to review the info. I set the logs up as CSV files here:
Suspect MAF Log
Good? MAF Log Any help greatly appreciated!
