There was no longer an issue once I installed and tuned the new ECU. it seems that the idle issue was contained to the standard ECU. Not something you want to hear though. The Adaptronic has no issue in controlling the same idle control valve that the standard ECU seemed to be having trouble with.

No. I didn't end up sorting the issue. Bought a stand alone Adaptronic ECU and had it tuned. Drives heaps, heaps better and makes more power too. Sorted the cold idle issue, the random lean surging (felt like it was running out of fuel) and now I can control thermo's from the ECU plus a...

G'day guys. My gen2 1uz does not have a resonator box in the intake and the AFM is right up close to the throttle body. There would be lucky to be 1litre of capacity between the AFM and the throttle body. In an effort to recreate the effects of having a resonator box does anyone see an issue...

Engine is supposed to be a UCF21. Here Is a pic of the ecu I snapped before it went in the car. Thought it might come in handy. Will check power duration to IACV tonite. Another thing I have noticed. This cold start idle issue seems to be related to outside air temp. Seems worse on a...

I wired it up myself using the 1uz wiring diagrams. Everything from motor to ECU was left connected. I got original ecu with motor. Here is a wiring diagram that I drew for the external connections to ECU.

What I don't understand is that if it starts up stone cold. And won't high idle, why doesn't the ECU open the IACV up more to compensate? It doesn't seem to function correctly until there is a little heat in the motor. If I stabilize the revs when it's stone cold and fluctuating, it idles around...

Thanks gloverman. Will check how long power stays on after shut down. I have previously adjusted the tps when I adjusted the base idle (setscrew on butterfly). Cause it was only idling round 500rpm when warm. I adjusted it as per the manual with feeler gauges between the stop etc to get the...

G'Day Guys, been chasing an intermitent cold idle issue for the last 6 months. most of the time when i start the ute cold, the 1uz's idle hunts up and down from around 1200rpm to 300rpm (nearly stalling each time). you can get it to stabilize if you give a light touch of the accellerator and...

Here is that close up. If I can help it I don't want to have to take the sump off again. Requires pulling the motor. Thanks for the help guys.

Don't know if my block is the same then. It isn't a "plug" as such. Just a blank area in the casting. I'm thinking if I drill through I will be in to the gallery that runs to the sump? See picture attached.

G'day guys. I have a 1uz that I put into my hilux that I have fabricated a custom sump for. My question is. Can I drill a hole and use a mid sump dipstick (through block)? Or are the blocks not the same? I can see the blank boss where the dipstick would be? Thanks.

G'Day Mate, Plastic covers still available?

G'Day Guys, am in need of the plastic cover that goes overtop of the ignition leads where they cross the motor at the front. Willing to pay what its worth. Thanks. Rob - 0428 322 035

Got one, thanks guys. Much appreciated.

G'Day Guys, am chasing an Auto bellhousing off a 1uz. Am located in melbourne, Australia. Ph: 0428 322 035 Regards, Rob.

G'Day Mate, not sure if you still need a front sump but i have one and am looking for a rear sump. I only really need the pickup and windage trays as i will be fabricating a custom rear sump. call me on 0428 322 035 if you still need one. Cheers, Rob.
