According to TPIS a stock MAF flows 529 CFM while a fully modified MAF flows 750 CFM. The MAF scalar tables seem to be linear in nature so is it reasonable to adjust those tables "up" the 40+% (to the max 255 value)in a linear way? It seems that the ECM needs accurate air flow rates to determine the correct injector PW. I appologize if this has been addressed before because I missed it.

 

Short answer is no.
If you look at table 6 it's already maxed out calibration wise.
There just is no way to get around the down sides of a MAF system, readily. If your needing serious air flow then a SD system is the only answer.

Once you remove the screen you've also really fubar'd the calibration, which has to be done to get some serious air thru the system.

Best way answer is running the Australian 808 code and going MAF, but you have to run the australian diagnostics. Best answer is going with a 730.

 

I believe grumpy meant MAP not MAF

How realistic is the 808 option? Has anyone in Australia seen fit to work on the software and if so is the hardware available here? I heard through the grapevine that the HAC might be available for some of the more creative computer literate types. Even with the limitations of MAF I still believe in its flexibility. The ideal system would incorporate both SD and MAF.
