reinforcing the last comment, has anyone noticed how long it takes for a car to warm up at idle? so thus you are running the car "cold" for longer? there has to be a middle ground. for me, it's taking it easy for the first 5-10 minutes of driving.

have you guys ever watched a F1 race car warm up from cold ... they rev them at a particular rev range at given tempretures as the car warms up to minimise the cold rattly pistons bashing around in the cylinders thus reduce engine wear ...

also i think somewhere i read the 75% of engine damage occurs in the first 5 mins of a car starting because it is outside its optimal heat range so getting the car to its optimal heat range as quickly as possible by driving it (within limits of course ... i dont mean that as soon as you start the car you have to dump a second gear burnout :D ) would be the best way to go?

Excuse the ignorance if i am wrong =P

They also heat the oil up to temperature before pouring it into the engine, to make further reduce the time it takes for your engine to warm up (which, in most cases, is to ensure the oil has enough heat to reach the proper viscosity).

IMO, 10-15 minutes is wayyy too long. Just a waste of fuel!!

Yeah but, the needle on the temp is just creeping up almost half way and the oil temp is just starting to move once I hop in. It's a small price to pay for proper maintenance.

No its not, thats 15minutes of the engine running at sub operational conditions hence more wear and tear, also running it at idle for 15mins would start to glaze the bores wouldnt it?

I think this would be doing more damage then its preventing, also your gearbox and drivetrain wouldn't be warmed up either.

get dressed for work, start car, set turbo timer on 10mins, go do everything else i gota, come back out about 7mins later and take it easy till is about 1/3 - 2/4 of the way up, then have a lil fun when i get to the 80-90 zones.. mmm windy fast roads *drool*

edit: although after reading what every1 has said, i mite not warm it up for as long from now on.. just a min or 2 then drive like a granny till she warms up.

    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.
