Think I figured it out! I had to turn MAP enrich down. I hadn't messed with that setting before, as I thought it was used for tuning the vacuum/boost transition. It's actually another parameter for the tune response, just like the TPS enrichment but it reads it off of the MAP sensor. So it seems...

I see you're back in the 7m club :-) . Looks like a nice one to start with, I don't see much rust! Sent from my GT-P7510 using Tapatalk

Whenever it's idling if I press the gas it will stumble for a second (sometimes the RPM will dip), and then rev like normal. If the RPMs are already up from a previous rev and I give it more gas it seems fine. I've tried all different values for the TPS enrich, none of them with a noticeable...

Bump! Any ideas guys? Would a video or log help?

I have my Maft Pro (software version 5.27) set up and running with speed density great except for some slight off-idle hesitation/stumble. I've tried to adjust all of the "tune response" settings but nothing seems to cure it, rather it only seems to get worse. I have a FFIM w/ 80mm throttle body...

Yeah I think so.

Saw a midnight blue supra parked in the autozone lot in hartville on Wednesday next to a FB RX7. I wasn't in the Supra at the time, but is it anyone here?

So that's what has been keeping you busy :). Great work it looks amazing. Now get a vid of it up :p

Finally some nice weather this weekend! Took a short video with my camera mounted to the rear of the car. Skip to 2:10 if you're only interested in the full throttle part :) http://www.youtube.com/watch?v=l_vr5wIiLoQ

Version 5.27. It was a little trickier to set up, but only because there wasn't as much documentation for the Supra as the 4.x versions. Love the MAFT Pro so far, but it would be nice to see some better documentation!

Sounds like it's $319 for one wheel, not a set of four. Seems pretty expensive for a no-name wheel.

Got the BOV and IAT flanges welded on the intercooler pipe back in March: Some updated pics of the engine bay: Got the engine running 90% perfect on the Maft Pro! Only headache I had was the lean spike at part throttle and vacuum to boost transition. I was able to solve...

We must be talking about different cars then. I'm pretty sure the one I saw was NA from the amount of rasp in the exhaust note :p

I think I saw the same one. Is it NA? It sounded like it to me.

I would. For the small amount of work it takes to add a flange for it (especially since you're doing it yourself), you'll gain a lot of idle stability and nice things such as idle up for cold start, A/C, etc. If you have a standalone EMS you would be able to get away with it easier.

I have a white spring (-9 psi) on order. Going to see if this helps at all. I'm OK with some flutter, it just sounds like it's surging pretty good even at ~5-8 psi (haven't tuned for more yet).

^^ This! I would never feel safe pushing my car to the limit on the street. Too many variables including traffic, road surface conditions, etc. Even better: if you have access to a local track, log some times with/without the bar installed and see if there is a noticeable difference.

If you have an iPhone or a Blackberry you can use dynolicious/logbox to log g-forces. Granted, it's not going to be as accurate as a professional meter...though it should give you a good ballpark figure and at a minimum be reasonably consistent between your own tests...

That is correct. Attached is a good reference I used that details out general upgrades to the fuel system. I didn't make it myself; all credit goes to the original author ;)
