    Is this what your Bosch By Pass Valve looks like?

    You want the 110 model, not the cheaper 103 and 108 valves. Bringle has a nice writeup including reference to a hose that tapers down. http://www.cygnusx1.net/Supra/TechTips/porsche_bov.aspx

    Driftmotion vs. HKS Fmic?

    That would be great to see. AMS = Alamo Motor Sports?? They used to sell the Cartech IC kit.

    Within 3 HC Points from passing air care. what to do..

    My HCs nearly doubled without the precat. As is is, they have been getting slowly worse over the last 10 years. The culprit is most likely a tired 20 year old cat since fuel control is good. Post up your numbers and we can compute your A/F, but I would be very surprised if fuel control is an...

    TPS Voltage Drop when Accessories are on.

    Consider that your alternator ground reference is the engine block. Also consider that the factory battery ground goes to the block, and the chassis near the under hood fuse box. You want to replicate that setup regardless of where the battery is located. The factory did not ground only to the...

    Driftmotion vs. HKS Fmic?

    That is useful info on an old school intercooler. I would like to see comparisons with the newer knockoff stuff on Ebay and other places. Any newer test data available from these mags that you are aware of?

    3P's TCCS Disassembly/Analysis

    I have not pulled the code out of the 42 pin MCU, but all indications from others who have are that is shares the same architecture and instruction set as the 64 pin version. There is an incomplete pinout of the 42 pin chip on Toyota Wiki http://toyota.kgbconsulting.ca/wiki/Pinout_42_pin...

    Driftmotion vs. HKS Fmic?

    The lack of any performance data is also really annoying. George Spears taught everyone years ago how to measure the performance of an intercooler, but I have not seen a single manufacturer publish even basic stuff like efficiency and pressure drop. If I was to go by the vendors the only...

    Driftmotion vs. HKS Fmic?

    Not to rag only on DM because all the vendors IMHO can improve their FMIC kit descriptions. Given the cost of these kits, the level of effort the vendors put in to describing what you get is abysmal. I've actually had vendors tell me to search the forums to find install pictures because they...

    Fungible

    SC; Hilarious stuff. Hmm, let's make the unbiased assumption that the Hummer will last 300kmiles and the Priius will be crushed at 100k. Now, based on that level headed assumption, we can show that.... S180 If you think the hummer is made of steel from Pennsylvania, well, I've got some fine...

    Fungible

    Toyota has been recycling NiMH batteries since the RAV4 Electric Vehicle was introduced in 1998. Every part of the battery, from the precious metals to the plastic, plates, steel case and the wiring, are recycled or processed for disposal. Using a first generation Prius battery as an example...

    What could be keeping my 7mgte from getting injector pulse and spark?

    Why not just hook up the MIL and check codes, rather than all this science experiment bullshit..

    What could be keeping my 7mgte from getting injector pulse and spark?

    You should get a code 12 if the ECU sees the starter signal for 2 seconds without any pulses from the CPS.

    Overheating issues

    I routinely see 225F on my wife's Volvo using the OBD2 logger on a hot day typically after a freeway run followed by city driving. I don't think 220F is anything to worry about. You may find this interesting. The factory gauge will start to rise at 240F (115C)...

    JZ Coils on 7M-GTE with dual ignitors

    The obvious concern here is whether the 50V abs max rating for the 2981 outputs are sufficient given the high flyback voltages generated on that igniter. I personally would want something beefier on the output if it was my car. But what do I know, I must just be a hater too.

    Still no fire

    Its pretty simple, you need 12V on the BAT ECU pin, and 12V on the IGSW ECU pin along with good grounds to E1, E01, E02 and you should have a working MIL light. Check those with a voltmeter and let us know what you find.

    7M-GTE need help identifying what year it was manufactured

    If the plugs are gray, its 89+, if the plugs are yellow/green, its 89-. Model year 89 had both types as it was the transition year.

    Grey Banana plug?

    Don't connect the two together. That would make a phased array, and the pattern would not be good. Just use the whip if you have only one antenna input.

    No start (spark?)...

    If the starter, rather than the starter circuit is bad, you can get a code 12.

    cooling the 7m better.... hopefully

    The fan clutch is easily repaired if the only issue is low silicon oil resulting in free wheeling and no lockup when hot. There is a tech note on how to do it. http://www.4crawler.com/4x4/Docs/FanClutch.pdf

    cooling the 7m better.... hopefully

    An alternator from the MK3 generation is about 60% efficient. That means for every horsepower at the alternator pulley, you get .6 hp of electrical power (about 450Watts). There is also another efficiency hit at the electrical fan motor, which is why the fan motor gets hot. There is no way it...
