View Full Version : Help with Maft Pro base tune

12-05-2008, 10:21 PM
Hi Guys I own a 1987 Toyota supra and i recently installed the maft pro with 4.8 and followed the quick setup guide and the car started up no problem. i was amazed as to how easy it was to set it up. The motor is a turbo 7mgte metal head gasket and arps. stock turbo, 3' exhaust all the way back, 2.5 intercooler hardpipes. my question is i connected the maft pro to the tuner pro and was able to download my settings. I ownladed them while the car was off. I was wondering if you guys would be able to let me know if i have everything setup as directed. and what i should change if anything.

Thanks again for all you help!!

The car runs good actually i have not driven it since it is stored for the winter but it starts up and idles with no hesitation. but the afr seem to be around 12-11.5 im not sure if thats normal. but how would i get it to idle around the 14.7 range

Thanks you in advance

So far, just what Bob has asked me to do. The latest thing was adjusting the lower end of the VE table. I'm driving the car today, so we'll see how it goes!

MK3dude I see that your in Toronto. Is there anyone up there experienced with the Maft Pro that can fine tune it in my 89 Supra Turbo Automatic. I'm down in Windsor and don't feel like going back over to Michigan to have the guy there play around with it some more. First he's too costly and second didn't do other work right so I don't know if I can trust him tuning since he hasn't tuned the MaftPro that much and especially not in Supras.
