Hi guys, I have been following along for quite a bit now, just starting to get my feet wet with tuning. I have a FT21 S4, just switched over to 750cc EV14's, went back to a stock tune with stock airbox to get them dialed in, now I am trying to get my HPX maf inline. I followed Julex's post and advice, used curveExpert to get myself a decent extrap/interp, massaged the near zero entries.
The issue I am having is getting my idle MAF values to sit down near 5g/s. I am reading 35-40g/s, I have tried changing the MAF wiring, but the result is the same, unless I reverse the +5v signal/return wires, then I see 5.10g/s but throw a million codes for other sensors. I must have screwed something up. Tomorrow I will have a peek and see if I can get it on the straight and narrow.
I should also note that the wiring harness is 100% refurbished, stripped back to the ECU pins, new connectors where needed, ICM delete done back to the ECU as per factory BEL harness, as well harness works great with stock maf and airbox, as well reads steady idle of >5g/s when used with my 90mm lightning housing.
Any advice would be appreciated
Post your MLHFM table. Make sure MLOFS is zero.
