Norbie had the same issue, and boost will not be an indicator of health as Limp home mode gives tha same result as Anti-Lag in rally cars, retarded timing and rich mixtures will spin a turbo wonderfully. The sensors have to come from Sydney so I probably wont get them till later on in the week...

For anyone who us getting terrible fuel economy, check your ignition timing at idle - If it's 5 degress BTDC your ecu is in limp home mode

is is possible one of your ignition power feeds is getting full time B+ and therefore the code memory is not clearing?

I was going to ask you if you had resolved this. I found this and Norbies thread on the 2J last night, and unfortunately I dont have code 12 generated until the motor is started. I tried the same test after ecu reset and the CEL just flashes normal whilst ignition is on. I also don't have the...

Nope, ecu reset and ignitor plugs swapped over, still Code 12. Which is probably a good thing after ordering $400 of sensors :veryhappy

damn good idea marco - i'll let you know in a couple of minutes

also as magetism can be diminished over time by heat it would make sense that the cam sensors would fail before the crank sensor as there is no cooling airflow behind the covers and they are bolted directly to the heads

UZS141 40P-40P-40P same as soarer with gs300 body plug as it's the same chassis as the JZS14x lexus. Shane (Cool1 on Toymods) and I wired up a MX73 here in Brisbane with the same wiring information with no problems. The cut only had a small bingle on the drivers side front so I'm wondering...

Thanks Marco, yes the shielding tests ok to ground. I'm just wondering now whether i've made some goof up in the wiring in the early stages of the swap that managed to fry the timing stages of both ecu's, although to date the only errors in wiring I've managed to find related to the air...

I've pulled them and given them a clean and no change, so at least the new sensors will eliminate that as a fault. The engine is definitely in limp home mode as the timing is locked at 5deg btdc. it must be getting a reasonable signal at cranking speed but going screwy once the revs rise to idle...

Thanks Peewee, Code 12 is back so it looks like the cam position sensors. The resistances when cold were about 1150ohms on the cam sensors but when checking the NE G1 G2 outputs with a frequency capable multimeter, I get G2 90hz, G1 48hz and NE 120hz. At idle at 600 rpm the crank is correct at...

Update: I had Toyota reset the valve clearances a few days ago - and on getting the car back had the Code 12 error. This got me excited as I thought we had found the issue with engine performance. It turns out that the goose that worked on the car used silicone to seal the cam covers and...

14 and 15 are the ignitors if that helps you

Any hints Gentlemen? I have ecu code 12 whic is supposed to be cam or crank sensor faults Crank sensor tested at 1250ohms both cam sensors at 1300ohms, all sensors tested all the way back to the ECU. The manual states that if the sensors test ok (the range is 950 to 1250ohms) that the ecu...

Damien, If you do happen to hear from him again - please let me know.

According to Neil at Rush Imports, Harry Lemmens fell ill some time ago and cannot be contacted.

It's an engineering nylon and used to be known as Synthetic Stone. Quote from DuPont: "Today, Delrin® is a mainstay of DuPont's engineering polymers line and is widely acclaimed as a lightweight but durable low wear, low friction plastic for engineering and automotive applications."

this is from the 2004 shelby cobra concept and from watching the video on the project build they have used delrin or similar to both allow the plates to slide and to seal the assembly I think this one is a Harrop creation and is probably the one you saw

Peter Scott supposedly had one of Harry's modified ecu's, and I would love to buy one but am getting no response from anyone I have contacted about his whereabouts. I'll leve it open to others on full aftremarket replacement ecu's

Does anyone know if these are still available or how harry Lemmens can be contacted as I REALLY want to buy one.
