    3P's TCCS Disassembly/Analysis

    We have received (dis)honorable mention in the IMOK mudfest. http://www.imoc.co.uk/forums/viewtopic.php?t=75023&postdays=0&postorder=asc&start=480 Thanks for your patience. Last night the board was working reliably. There is light at the end of the tunnel.

    My OEM Radio Upgrade

    This has been covered many time before. The tundra radios up to 2003 work just fine, they are the exact same radio as the Camry posted by the OP. You can also interface to the original Supra amp under the seat if you buy an external amp radio as discussed here...

    Obsolete MKIII parts; are there any?...yet?

    Many years ago I remember people scrambling to get the last few TDSE kits left. I would be shocked if they had found some more since then. The enhancement was a remote fob integrated with the factory alarm.

    Replacement key code

    to me it looks like R6104

    3P's TCCS Disassembly/Analysis

    I loaded this code into IDA and it looks like typical ECU code form Toyota. Without knowing how the sensors and such are mapped to the MCU ports on a 1J ECU, it is hard to proceed further. The data file you sent is a little weird in that it has 32770 bytes of data, but the first 20482 bytes are...

    3P's TCCS Disassembly/Analysis

    Yeah, me too! This project is being worked pretty hard, but has been slow going. If its any consolation, it works some of the time, but that's not good enough to make it usable in the field, and tracking down the problem has been very tough. ---------- Post added at 04:36 PM ----------...

    Fresh build, oil seepage from Rear Main

    I'm with IJ. I had a differential leak that would not go away (I replaced the seal 3 times) until I moved the seal location relative to the halfshaft. The groove was barely detectable but it was enough to cause a leak.

    Teamslow's 7m SuperStreet Build

    Very nice build. What intercooler piping kit are you using?

    At What temp will Fuel Pressure Up (FPU) system switch on the VSV?

    So your poor warm starts problem remains, and is not the FPU VSV?

    Possible Damaged Vane Type AFM

    NE is clocked on the rising edge at the MCU, but I can't remember if there is an inverter in the signal conditioning amps between the CPS and MCU. G1 and G2 are asynchronously latched, and checked at each NE event.

    Possible Damaged Vane Type AFM

    Typically the resistance strip is scalloped with about 8 steps in the full range, with shunt resistors used to tailor the resistance for each segment, so the rate of change (second derivative) varies with position, but the resistance must be monotonic (first derivative>0) . This photo shows the...

    Possible Damaged Vane Type AFM

    You are reading too much into a translation from Japanese to English. What they mean is that the resistance varies smoothly (like a wave) through the range of motion of the flap. Rest assured that it is supposed to be monotonic, otherwise it would be useless as an AFM. THA, discussed on page...

    Possible Damaged Vane Type AFM

    If its like the 7MGE ECU, then the AFM and NE signals are used to compute VE. There are a few correction tables based on coolant and air temp, as well as battery voltage. Given the way the AFM operates, the voltage returned is linearly proportional to the resistance. The voltage cannot be...

    Possible Damaged Vane Type AFM

    I think you already found your problem. The AFM is bad in post #1, then post #6 is good. I would suggest it is intermittent. Try putting it in a freezer for an hour then remeasure before it heats up.

    E-brake shoes are the same as a Toyota Sienna 04-08?

    Is the point of doing this that the Sienna shoes are cheaper, or is it that the Supra shoes are getting hard to find (discontinued?).

    I see that for 92 the exterior color black is not called mica ruby pearl. Was it changed from earlier years?

    3P's TCCS Disassembly/Analysis

    Yes, I know where in the code they check for fuel cut, RPM cut, and so on. My problem right now is getting my extender board to work reliably. Damn thing is being a pain in the butt.

    At What temp will Fuel Pressure Up (FPU) system switch on the VSV?

    Well, I'd exhaust other possibilities first before I blamed the ECU. The FPU signal comes of the same MCU port as the ignition and injector signals and EGR. Check for proper operation at the ECU itself to rule out wiring issues. The EGR signal is also worth checking, they share the same ECU...
