Hello Jeremy, I checked the O2 output in the diag port, and they are cycling as per normal, and have never touched them before. Every now and then it will go back to 700rpm, so something intermittent is causing this. The thing that annoys me, is the car runs perfect otherwise, heaps of...

yeah, I might give that a try. But do you you think a fault there could raise the rev's at idle that high ? 13-1400 is a fair wack. I thought it might be a fault in the cold start circuit ? Ive pretty much exhausted most obvious causes, and now only left with the ECU as a probability. I...

Ok, My idle on start up is about 1350rpm, hot or cold it doesn't move from there. Just idles fast regardless. Does drop back to about 1000rpm in drive. Things I've tried, clean and inspected ISCV, resistance test according to manual. Tried 3 different ISCV'S ( these all worked on another...

Haven't got much done on this lately, just been doing some driving and planning a few bits and bobs, oh and trying to get the a/c cooler than present. One thing I noted when replacing the ac compressor was the crappy looking ground wire. It doesn't look heavy gauged enough, and secondly is...

Love the Merc :) Do you know what year then engine ecu is ? It looks like the pins from a 92.9-94.9.

Hello Gloverman, It doesn't have the diagnostics port wired in. Ive got all the wiring diagrams for the car, so I'm sure I could put one in if needed. Can the knock sensors really kill performance through the entire rev range ? I always thought you had that scoop out of the graph up top in...

Does anyone know how much timing advance is pulled when the IAT reads too high etc, say 35 degrees plus ? The LS1-LS2 engines pull a fair amount of timing with heat soaked MAF sensors, and rising intake temps, and hence the popularity of the OTRCAI. I just did a 450 km round trip in my soarer...

These do look very interesting, would like to see a compressor graph to a comparable oil fed turbo.

8 pack, yeah last one I bought was from Germany, about half the price of aus. I don't touch second hand ecu's though. The ecu, I will be wiring it to is a series two celsior, I had a look on the net last night, and now have all the pinouts. It looks pretty easy, group injection, so 4 wires...

8pack, I think the EMU is a really good unit that should give equal to standalone performance, without alot of the head aches. So yeah point taken, have been thinking along those lines for a while. Hopefully Cihan will be in QLD in near future. Wiring the EMU should be interesting to the...

8 pack, I'm running a EMU on my 1J, not tuned yet though. I have looked into this for the 1U. It does essentially eliminate the IAT which removes some of the issues with ignition pull with air temp increases.

Ok, so Ive been driving around the coast a bit lately and its been quite warm. Car runs great when cold, and as soon as she gets hot, the power goes. Now as far as I can tell, it aint a water temp issue, its generally steady as a rock and sits below 82 degrees most of the time, it will...

Yeah it was the same with both ecu's before the caps. Beezer, I not sure of the knock sensors ? but when on the dyno it showed no sign of knocking, just down on power. When its really dead, you can basically hold it in first gear, floor it and it just makes alot of noise, eventually revs...

34 p 22 p 16 p 28 p I'm pretty sure thats the pins, or thereabouts.

Ok, thanks for that, And regarding the ecu, I think the one you have is the earlier series one ecu ? perhaps not. I'll just check

Sideshow, MiNes stated that the "condensors" as they call it, may need replacing, and that was going to be around 250 bucks aussie, so I just did it myself. Some of the caps in that ecu were a bit tired looking, but not terrible. The stock toyota ecu looked about the same, and as you say, just...

"Goals: A 1400 hp (approx) car capable of low 7sec passes and still be somewhat streetable." The key word here being "somewhat" absolutely love it :D

Sideshow, I actually sent this loom to you, and as far as I aware, that side of things is a ok, well you are the best in the business :) Its great you coming to QLD, and I sure will drop by if need be, I can get you to wire in a diagnostics port if need be. Ive replaced all the caps in both...

Hello fellow Lexthusiast's, I will cut great to the chase, I have a 1UZFE in a 76 s class mercedes. The donor car was a 1994 Celsior/ls400. Its running std ecu, and 4 spd trans. Now when I disconnect the AFM, it runs great, heaps more power through out the rev range, heaps more torque and...

Hello people, I'm sure some of you are aware of the Apexi super ignition timing control (S-ITC) I'm wondering if anyone has used one on the 1UZ ? There seems to be a general consensus that Toyota have very conservative ignition maps under 3k, to improve the "smooth" feeling of the...
