I have not pulled apart the IAC recently. Although about 800 miles ago before I put the new motor back together it was cleaned. At least around where that black ball looking thing seals. I did not ever take it apart further than removing the whole unit from the manifold. It does click like...

Reset the TPS? you mean calibrate? I get no code 51 so in my thinking the TPS is in it's operating range, but maybe it still is snapping shut too much too fast and doesnt throw a 51? I also think I need to test the dashpot. HVYMAN- If i back it off a couple turns (to idle around 750) it still...

So back when I didnt know what I was doing I thought it was a good idea to turn the idle adjustment screw on th throttle body counter -clockwise a bit to bring my idle speed up. Since then I have heard that it shoudl always be closed fully clockwise. Well, the problem is if I leave it fully...

says in your Sig you have an Apexi Neo. Have you noticed anything different with that? Maybe a wire connector came loose or something?

Plus the carbon fiber parts arent cheap that you have there!

Is your fuel pressure on your afpr still reading normal?

I have an safc but i am really finding it kind of pointless on a bpu 7m. I could see the benefits of maft by getting away from the afm. need more time with a wideband to tell but it seems to me the lex/550/afpr route is tuneable enough with the afpr in conjunction with vf and a wideband. But i...

Turned out to be a couple boost leaks. Pulls like a freight tain now. Only problem now is during wot at the top of the rpm range the vf signal goes full lean. At any other time my vf is perfect. I thought i remembered reading a while back that vf doesnt monitor open loop so maybe im alright? In...

Thank u..that makes sense now.

Hmm. With the hot intake temps i got and sluggish pull im certain i got boost leaks again. Briefly can u describe how a boost leak could make more air flow past the afm? It should just let more air out of the system not affect how much air the afm sees or am I way off?

Thats true i should try to monitor vf and keep that happy. As long as vf is at 2.5 ish can u hit fuel cut?

thanks...i'll play around with that when I get the WB back on. I used a portable to tune and where i have the AFM screw set was where my AFR's were good so i don't want to play with that until I know what's going on. But when I was tuning it the first time all the way in vs. all the way out...

I have lexus afm/RC 550's, afpr, fmic, and and safc but the safc is not hooked up yet. I thought for sure id be good past 15psi with that. Wondering if the tune has anything to do with it? I will know more once i get my wideband back on there and get the new piping. Then i will be ready to...

Well i just thought it was weird that I'm hitting fuel cut at 15psi with my mods (lex/550). Hopefully, when I get new piping and upgrade to the DM 11psi wasegate that will help. I won't be happy forever at 15psi on a 60-1.

Is code 34 actually a boost leak or is it fuel cut as well?. My boost spiked to about 15psi today (turned boost controller wrong way) and when i got on it the car lost power for a split second and CEL came on and went away after bout 10 sec. Pulled codes and had 34 after that. Im curious because...

Cant leave threads unresolved...ended up just replacing the thermostat, coolant temp sender, ecu coolant sensor, radiator cap, and flushed and refilled the coolant. All better! I guess when everything else fails just replace it all. 99% sure it was the thermostat stuck closed and not letting...

Lmao, I thought the same thing when I got my thermostat in the mail.

Cool man, that would be sweet. I still have the problem of matching the paint. Has anyone ever had experience with this site? http://www.toyotareference.com/supra/1986-1992

So if you look closely on the rear wheel well i have a couple rust spots. Also the front driver fender is a different color white than the rest of the car (came this way from the PO). My car is not a show car and I keep my money in the motor not cosmetics. Therefore I'm fixing these two things...
