Do you have a strong battery with good connections? Another possibility is the temp sensor for the ecu. It is the one with two terminals ..the one with a single terminal is for your dash gauge. Unplug the ecu terminal and if the car starts better then that one needs to be replaced.

ECU is in the LHS kick panel but you don't need to access it - disconnect the sensor at the sensor: follow the top hose to the block and you will find two sensors - just pull the plug off the one with two wires.

Is the car on E85? common problem with E85 cars. Just keep cranking lol

Common with a lazy tuner :)

Mine starts in any temperature 1st go, and idles fine.. just doesn't drive very well for the 1st minute haha

Out of interest, how often do you start / drive it? Does it sit for weeks/months, then still start first go?

Have an R33 GTST track car with lots of mods, including E85. It starts fine when cold if it's run regularly, but if it sits for a while (> a month) it's very hard to start - crank until battery goes flat, recharge & try again....

Probably once every 2 weeks and yes it just sits around in my back yard. Last time I drove it was at the Sparesbox skid pan (performed terribly, never take a track car to a skid pan, it doesn't skid very well)

E85 is fun, there's a fine line between wetting the plugs and not starting and not enough cranking fuel to get it started. Then there's all the other dimensions of intake air temp, ethanol concentration, etc. I find adding a good amount to the initial prime table makes all the difference. Happy to send you my kebabtech tune file for R&D if you like.

    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
    • Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
    • And now the bloody flapper is jammed slightly open. Lazy as all f**k in 3rd-5th (very hard to convince it to make much boost before you run out of revs), but will make 12 psi in 1st, which shouldb't be possible with a 5 psi spring and controller set to <10 psi. Methinks I'm lucky it jammed where it did, rather than fully closed. It's actually a well weird situation. Careful examination of what's happening in the back of that housing when the gearbox comes out and all the other stuff (injectors, AFM retune) is supposed to be done, next week.
    • The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.
