Thanks Dan and Costa and Sebastian.
Crank angle sensor was one of the first things we replaced trying to fix this.
The emanage shows all the inputs it is monitering as fine. We have tested the wiring for the things the emanage isnt monitoring when its all hot and there seems to be no issue with the wiring.
The emanage shows the stock computer literraly pulling timing right out of it but we have no indication whatsoever as to why. evey sensor on the god damn engine has now been replaced. the loom has been tested...the earths have been tested and tested again...im just at my wits end...so much so that I have put up an EOI on parting it out.

So have u tried removing the butterflies in your thermostat?? Sometimes that may cause your problem at least in nq any way also has all your testing been with the same fuel itself?? Some servos have been known to put crazy additives in the fuel cause weird •••• to happen? My only other suggestion is try what it's not try replacing the spark plugs etc but to me if it's only when it's hot try the thermostat butterfly's make sure the not suck close or something stupid.

Try testing the actual loom itself for resistance/continuity. You may have a snapped wire inside the insulation that cannot be seen or readily detected unless it is faulty under vibration, heat etc.
Something in the conversion/reconditioning process that is causing heat sensitivity.
3. as it gets warmer still it will start cutting fuel and ignition completely randomly, with any throttle input or even just idling it will cut fuel and spark and die. then it wont spark as you are trying to fire it up. 4. if you let it sit and cool down the symptoms will downgrade and it will become drivable again. 5. if you let it cool completely then it will run like a champ and make super power again until it starts to warm up.
Spark and fuel are related and rely on the same sensors to make their calculations. My recommendation is to use an oscilloscope to get a baseline trace of what is NORMAL and what is NOT NORMAL when the engine is warmed up on all sensors/modules, starting with the ignition module.
This problem can be fixed, but you just need to find out what the problem. is. I've got a hunch it is the loom given you have changed a lot of the equipment/sensors.

costa Ive heard a few people say the 1j ecu doesnt go open loop until its warmed up...if this is the case, could it be that the output of one of the sensors completely fubar, but the ecu isnt doing anything about it until it goes open loop? hence the problem when its warm?
Others have also said that the ignitor sends a signal back to the ecu once its fired. If the signal wasnt getting back to the ecu, or taking too long. and the ecu is waiting for it. Do you think that could look as if the ecu is pulling timing and even completely cutting spark wihout throwing a code?
the sparky at the workshop says he has tested the loom several times when hot and when cold and he cant find anything wrong with it. so i really dont know. Id take it somewhere else for a second diagnosis..but this is the place round here that other people take their stuff to when other tuners cant figure it out. So theres really nowhere else to go on this one lol

Just bit the bullet and decided to put a haltech platinum 2000 in it...all new sensors and ignition system. ill sell the standard ecu's and the emanage and stuff.

no idea then man with me i find it gets so hard with high modified cars becuase there ends up being so many other "factors" involved with diagnosis! sorry!

It's a long shot, but it's possible your ecu had leaking caps before they were replaced, this leaking may have damaged some circuit tracks in the ecu, causing the problem.
The unknown ecu you tried may have leaky caps with the same problem.
Try your ecu into another car that you know is running fine. If it still runs fine your ecu is ok, if it has problems then it's your ecu.
.5% chance of this theory being correct as I've never heard of any ones car being this affected by leaking caps and then to have a second ecu do exactly the same thing but if you want Harley I have a spare ecu you can use to test it for the third time. PM me if you want it mate. I'm taking Monday off to take my car to get tuned so I can express post it to you then if you want.

Wow thanks for the generosity sebastian. I appreciate the offer, but we will just put the haltech in. Simplify everything and then we will know exactly whats going on with proper logs ect, instead of guessing at unknown symptoms nobody has ever seen in this combination. Once again though, thank you for the offer. Its greatly appreciated.
Thanks also to all that have taken the time to read the thread and offer advice. I will keep it updated once the haltech is in.

lol mate it will be for sale. EMU with software, manuals and universal harness, with a 400rwhp tune on it for around 1000ish wire it up with a gt30 series turbo for wheelspin goodness lol

yeah im not sure what it was mate. In the end we had tried 3 different sets of coils, 3 different ignitors, and tested the wiring umpteen times with nothing out of the ordinary showing up. It had us, Greddy and several other tuners completely stumped.
But whatever it was, its gone now and going like a champ next step is im240 and engineering. Thankfully the boys at PBE have a 5 gas analyser so we can make sure it will pass the im240 before I even book it in...WIN
oh daniel if your interested mate, I have that emanage going for around 700.

Thanks , 11th August . bit of a weird story . 1st pregnancy and baby , 2nd child .
After 7 years of trying for kids ( 4 lots of IVF ) , we were told it wasnt going to happen . So we fostered last year . We have a foster daughter already who turns 3 in july .
We started seeing this little girl in Spetember , and she came to us full time in Nov . 4 weeks after she came to us , long term ( permanently ) we found out my wife was 6 weeks .

Wow mate thats incredible! You guys are blessed, A friend of mine has been trying for kids for 24 months to no avail...Meanwhile another friend of mine that was told she could never have kids is about to have her third accidental one. Whats this world coming to?

Thats Awesome News Daniel!! It's Good to see good things do happen to good people. Congrats mate. Baby seats are hard work in the back of a Soarer but its all worth it. lol
