Justin

That's a really useful clue then but I don't have the information to work out how to reproduce it via the diagnostic connector. Perhaps some undocumented "feature", Mark may be able to work it out. I can see how to do it using the coolant temperature sender without drama. To avoid confusion caused by my ignorance can you confirm which diagnostic connector we are talking about. I tried the cold coolant trick on mine just now and it certainly works, heaps more mumbo and sharper shifting. It does seem worth chasing this down.

Thanks

Roger

Justin,

One other question, what type of Soarer was it that was involved in the original experiment pre prang?

Thanks

This is awesome info! If we do fool the ECU into thinking it's still cold does that mean the cold start injector is going to be constantly running?

Hopefully not. The temp range we are talking about should be well above the cold start range but below normal operating temp. I would think that the cold start injector would be timed as well but I'm not 100% sure.

Where abouts is the cold start injector mounted on the 1uzfe?

Roger, how did you do the "cold coolant trick"?

Mark, did you discover if there are separate sensors for the ECU and gauge or do they both read from the same one?

Funny you should ask,

I took it out Stone Cold and thrashed it senseless. I have an R/C Air conditioned Garage (really) which goes down to about 3 degrees. Perfect for these sort of tests, and keeping warm on cold nights and cool when its 44 outside. It was a bit hard to justify to my wife fitting the 11 KW Carrier Ceiling Cassette originally but this experiment fully validates my decision IMHO. I think an appropriate resistor to temporarily re-calibrate the coolant temperature sensor and a switch on the console would be the way to go. The switch should be subtle, preferably not the fake missile arming style red shrouded knob-jockey specials that Hyundai rice drivers use to turn on their underbody glow lighting.

Roger, as a hyundai daily driver I am suitably appalled and outraged by your slanderous comments.

Pistols at dawn Sir!!

I suppose you'll be holding your pistol horizontally in the "gangsta" style Perry??

I shall place a projectile in his gluteus maximus. I also am far ahead of the times and shall be holding said pistol completely upside down, which will be all the rage in 10 years time.
