[LEGNA]

Just monday a had my car so called tuned by a so called tune shop and to make the story short the guy could only get me 274 hp @14 psi now... im no tunning expert but i no thats not the best my car can do needles to say i need a maft-pro experienced shop if any one knows please post so i could get this car to its full potential..LOL just as i was ready to leave i asked about the other parameters and if he adjusted any and he said ..DUDE I REALY DONT KNOW WHAT THE REST OF THEM ARE FOR...

i know a guy who knows his shit. he hasnt tuned with the maft pro before but he will for sure tell you if he can get a worthwhile tune out of it. ill be trusting him to tune my supra when the time comes...PM me if youd like his number. hes in CT as well.

it's not that hard to tune it yourself. You only need to worry about closed loop operation (above 75% throttle or somewhere around there) because anything less and no matter what you do the ecu will do it's best to keep it around 14.7 in open loop. It's really easy to set the outo tune if you have a wide band also.

got the loops backwards, closed loop is with 02 sensor feedback (stock o2), and open loop is startup and WOT.

I gonna look into the auto tune...i thought it would correct its self...not auto tune

it's not auto-tune, per se, it's AFR tracking. datalog, then adjust the MAFTpro accordingly, and it's tuned. (from what i understand)

im not sure what i have doen to my car, but it's stuck in open loop,

i have full control over the fuel any rpm/ load..

and it's really making my car hard to tune and get good gas millage.. :3d_frown:

shaeff, its not auto tune, but you can instruct Maft pro to keep A/F between lets say 11.5 to 11.9 to 1, and it adjusts the A/F signal to stay within those limits at WOT based on the wideband signal. I think that the recent update now has that A/F tracking option for cruising as well which tells maft pro to maintain 14.7 for example at cruising. (If I'm wrong please someone correct me). Off course it also offers dataloging for tuning as well.

oohhh. that's even better! (if that's how it works) i really haven't gotten too far into the whole tuning with the pro yet.

ooh

scarey

I won't gamble an engine on that feature Hell all standalone can do this but no one in thier right mind would give the O2 that much authority over the motor at high RPM, high HP.
