    cold running Vrs hot running power drop.

    coolant temp sensor, they tend to go bad, and force the car to think it's 250 degrees F. A way to test it is to unplug it completely, after the car has warmed up. What computer are you using?

    Parts Parting out 1992 SC400

    what's wrong the chassis? I need a part out of the rear for the turn signals. It's underneath the panel on the left side (driver side) of the vehicle.

    1uz-fe, are you happy?

    Well I'll be honest, I have a stock 1uz with a holset hx35, I like the torque that it provides, makes for a great street car. I don't need to down shift...ever. Boost comes on right away, but the higher end makes me a bit upset. BUT there are a lot of cons on my setup, stock headers, merged...

    my 1uz mk3 project

    yeah redline is 6500, I have no idea about rev'in to 7 though. Unfortunately I'm running a hx35, I think it's a bit too small honestly, and it's becoming a restriction. It doesn't feel any faster about 10 psi really. That or my exhaust piping is way too small (which I think it is). Boost...

    my 1uz mk3 project

    I have a turbo rear end, I have a 3.9 also, but I'm using a w58. But even then, that's still really really poor gas mileage.

    Yeah I have some on supramania, I posted in 42quick4u's thread, or whatever, he's posted on your thread here a number of times. How bad is your mileage??

    my 1uz mk3 project

    lol mileage? whats that? A full tank nets me about 260 or so, and I have the car running as lean as possible...I think I need new plugs ha ha, but mileage on my stock SC4 wasnt' very good either.

    my 1uz mk3 project

    Ha ha, yeah a lot of people get confused about it, and of course had I not had a SC400 prior I probably wouldn't have known this issue either. I'm using it for both, it's easier to diagnosis sensors with it, well the main sensors anyway. Also have fun with trying to tune it with o2 sensors...

    Standalone ECU Going Adaptronic thread!

    Yes please let me know, but it's not a guarantee though, I might follow your footsteps and go standalone. I'm not very familiar with Innovate unit, I do know the AEM only need 5 volts. Another thing, on the AEM EMS, it won't connect with less than 12 volts, even though they are two different...

    my stock gauge says 4K when I'm at redline, I've confirmed it with the SAFC. SAFC says 6450 while the stock gauge shows 4000, I think it actually says 4200 or so. Don't forget on the SAFC when you do the vehicle select as a 4 cylinder and not an 8. The ignition system on the 1uz is like...

    Standalone ECU Going Adaptronic thread!

    hey KC, Are you going to get rid of your other stuff? I MIGHT be interested in some of your stuff if funds allow. Anyway, out of curiosity why are hooking up your seat heaters to the adaptronic?

    hmm I wonder why Toyota put it there then, maybe an issue with captivation in the fuel rail?

    How is everyone installing their Fuel Pressure Regulator (FPR)? I'm a bit confused since we have two of them. Are people installing it on the right (USDM Passenger) side of the car?

    Standalone ECU Going Adaptronic thread!

    Oh really? How much does it cost? I might look into it, I figured the EMS would be the most cost efficient way of doing it
