That sounds dangerous. If it is fuel it'll ignite in the exhaust at some point. I doubt it is fuel. If it is fuel then I can only imagine this can happen (with the engine running) if several cylinders are not getting ignition spark and even in that case I doubt fuel will run out of the exhaust.

First of all, I'm not going to attempt to tune the car on any major boost. It is going to a tuner. I'm considering EGTs on each cylinder or at least one on cylinder 6. The Apexi is a standalone and it monitors knock. There is an aplication called CoPilot that can autotune the fuel and the ignition if given a reasonable basemap and target AFRs. I was considering using that and just drive nicely without getting into any real boost. I just wanted to lean it out a little off boost so I won't waste so much fuel. The milage is really poor at the moment. I would also like to know more about how to tune. Like what are acceptabel AFRs and EGTs ect. I'm also getting a new map sensor that'll go to 3 bar absolute. So I need to be able to do small changes to the map so it'll be ready to go to a tuner.

Did a new AFR map converted to bar.

I have a wideband as I just wrote. The x is of course rpm Y is kg/m2 24000 kg/m2 is around 2.35 bar absolute so it'll be a map that goes to 8000 rpm and 1.35 bar boost. It is the base map of the Apexi. 10000kg/m2 is around 1 bar so it'll be the transition between vacuum and positive boost. And of course the cells in the target AFR table are equivalent to the log table. What I'm primarily looking for is where I can safely lean it out to get better fuel milage. And to what target AFR in those areas.

So I have wired in the wideband and done some logging. I have no idea what I'm doing so any help is appreciated. I have attached the log file and an Excel document that I made to be able to calculate the corrections needed. What I'm mostly in doubt about is what target AFRs to go for. I have compiled a set of target AFRs for rpm and load using the stock MAP sensor. I copied the target ARFs from the stock map from the Power FC and replaced the 14 with 14.7. What do you think? Are they way off? POWER FC.xls

What is the stock 440 CC lag time?

I've had two Apexi FCs. The first one had the 4.10C firmware. The one I have now only has 4.10 (no C) I read at the Datalogit group at Yahoo that the 4.01 had issues with the boost kit and you should get the 4.01B or better to make it work. Now I wonder if that was a typo and should have read 4.10. Does anyone have any other firmware than 4.10x (-/b/c) ?

I've bought an 6AN adaptor for the stock fuel rail. When I look at it I think with a 90 6AN fitting attached it will be very close to the throttle. Does anyone have such an adaptor with a 90 fitting that actually clears the stock TB? This is the adaptor I have: http://www.ebay.co.uk/itm/AN-6-6-JIC-Fuel-Rail-Adapter-Subaru-EJ20-GDA-WRX-Bug-Eye-Onwards-/170883743385?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3ASupra&hash=item27c976fe99

I have a strange issue with my Apexi Power FC. I noticed that it had a high idle and I checked the sensors. I can see that the Apexi thinks the AC is on. So I check the pin 34 at E10 plug and it is ground. When checking the TSRM for the US spec Supra I can see that ground should indicate that AC is off. ???? So I de-pin the plug and start the car and now the Apexi thinks AC is off. Ground Pin 34 when running causes the Apexi to detect AC on and raising the idle. What is going on? Is the TSRM wrong?

I've got a stock JDM car apart from UK spec turbos and UK spec cams. Everything else is stock JDM and no boost controller (cats in place). I've installed the Apexi Power FC initialized it to the basemap and now I need to have a wideband bung welded into the downpipe. Would you consider it safe to run the above configuration without having it tuned and without being able to see AFRs? I would normally not do that with any basemap for a standalone, but since the Apexi is build for the Supra and the engine is virtually stock I'm thinking that the basemap could be safe enough to do that.

Hmm. it turns out the sub throttle TPS was ok. Adjusted it and plugged it in and the 47 code went away. Then I emulated the main throttle TPS with a set of resistors according to the TSRM connecting IDL to E2 with a wire and VTA to E2 with a 2.4 Kohm resistor, VCC to E2 with 4.7 Kohm. Then the codes went away. So an unplugged TPS on my car gives an error code.

I'm referring to this: HINT:

Had a second look at the sub throttle TPS and now it measures correctly. So maybe I was checking it wrong when on the car. The throttle TPS is still not working. But again unplugging the TPS should set the error codes, right?

I have a Supra MKIII with a 2JZ-GTE engine. I just finished adding a hydrofan setup from a JZA70. It involves some wiring. Somehow I have swapped +12 and 0V on the hydrofan computer. So it might be toast. But I have another one. However my problem is that I now run in limp mode and the error codes are 41, 47, 77 and 89. When I discoved my mistake I unplugged the hydrofan computer and fixed the wires. Then I tried a new ECU. Until this point I had only 41 as code. Then 77 and 89 appeared with the new ECU. Swapping back to the old one didn't fix that. So I tried to plug in the throttle body TPS plug into the sub-throttle body TPS and the 41 code went away and a 47 code appeared from the missing sensor (left the plug for the sub throttle unplugged). Then I swaped back and now I have both 41 and 47 codes as well as the 77 and 89. I have measured both TPSs and they both have infinite resistance between VTA and E2 (that should not be the case). The throttle body TPS has also infinite resistance between VCC and E2 but the sub throttle body TPS has normal resistance between VCC and E2. When I look at the trouble shooting section in the TSRM it states that unplugging the TPS should not result in error codes. I find that hard to belive. Can anyone confirm that the error codes should not be set if the TPS in unplugged? As far as I can imagine an unplugged TPS would give the open code for VTA just as infinite resistance between VTA and E2 should. Would an unadjusted TPS give error codes? (not according to the TSRM)

I'm looking for the TPS for the throttle and the sub-throttle: Partnumber: 89452-22090 89452-22080

I'm looking for a Greddy 60 mm warning temperature gauge. I actually only need the sensor and the wires for power and the sensor, but I'll settle for a complete set. The gauge itself is not important so it can be any color and even missing.

MT or AT ?

UK or JDM?

What are the offsets?

Do you have this: http://www.mkivsupra.net/vbb/showthread.php?260996-Slipring-1998

Damn, too late again. I'll take it if the deal falls through.

Does it have a thermostat?

Btw the test costs 1000 euro in Hannover. And I think it is not too much compared to what we pay for our cars and the modifications that some do to them.
