[Guest sl1d3r]

Hi guys checked my ignition timing the other day and had some funny results got a brand new gunson advanced timing light blocked the pins in the dignostic port cliped on to green wire started her up and got a reading of 26deg before tdc now i know the car should be 10deg but it was ticking over fine and runs fine !!! so either my timing gun is shot or something isnt right just wondering if anyone has any suggetions ?? on and how do you adjust the timing on the 2jzgte ??? your probly think this is a dumb question but i am new to the mkiv supra cheers

You cant adjust the timing on the 2JZ GTE, its set by the ECU. And, like I asked on the other thread, why did you need to check it anyway?

That was a different member Swampy, or so it would seem.

It was, but the same question still stands

Here's a little trick of the trade: Don't clip a timing light around the green loop of wire in the igniter connector; it's just the designated decoy. You can use a normal timing light just fine by clipping it around both of the wires going to the coilpack of cylinder one. The arrow on the pickup points towards the sparkplug, just like on a HT lead. It does mean taking the spark plug cover off, which is a pain when you just want to check the timing.

This i havent heard but if the timing is set to 10tdc on ecu but out at the car surly you need to marry the two up ??

Silly question but has your timing gun got buttons to calibrate it, normally run the engine adjust gun so it reads zero then you press the trigger to get the correct reading.
