Ecumaster forum

your target map looks a little odd and flat....

my 1jz was knocking a lot before i got it tuned up, but i have massive problems with bad coils too. Lets see your map

woa your VE is a big mess, try equalising the large jumps atleast

Got 1jz gte, whats the problem?

copper, been told to avoid fancy ones in the jz

Seems my wiring was correct all along, the problem i had was with a set of spark plugs that i put in last week ans have done 120miles... they had coked up because of the crap coil packs and i never bothered to take them out to check them. i was using an old cleaned up set to test everything else. Ne...

I have now fixed my EMU... I built second loom up too eliminate the one thats on which made no difference at all. Went back to the first loom and tried a second set of coil packs which didn't work. Pulling hair out and getting annoyed i pulled all coils and sparks out of engine and plugged them all ...

I have been running like this for a year and havn't had anything change, fans etc havn't moved.. But i will check wiring to see if its getting interference from somewhere.

my timing is normally correct, at the moment i have a different problem, i may have damaged the emu when i tried out these 1g fe coils. They are wired up to number 2 i am sure and not 3. I have put the old coils back on which are fine except for spark leaks but i am getting a new problem, with ignit...

Not sure if i have a wiring fault which is very plausible or have killed the ECU while messing about with wires. First of all i can access the ecu and go through all of the options etc with no trouble, upgraded firmware etc and that side of things seems fine.7 What i am getting at the moment: -Turn ...

Injector size is not important. I have standard 370cc standard injectors in my 1jz gte vvti, my tuner had to set them to 500cc to get the car to run right. I am now changing to 550cc injectors and my tuner said to set to around 700cc just to takr it to be tuned again as it wont be perfect. So just c...

Dwell was set by the tuner, dont know if its too high. Top of the 1jz gets very hot and could do with better cooling.Its a common problem with cracking coils with these wasted spark ones. But before i buy anymore i will try this as a cheaper option, also people have said the engine runs smoother wit...

I have no igniter, i have 4 wires to the coils, negative, 12v ign switched positive and a signal wire which requires a positive 5v to trigger. There is one thats only for oem ecu.

Sohow do i wire it upto the ecu?

can you upload your files for you ecu setup?

Ive had trouble with my 1jz vvti, firing is the same on 2jz vvti so should be able to help

Can you attach your setup files for your emu so we can have a look at your settings?

I have had major issues with my 1JZ gte vvti coils, they keep cracking up and i have had 4 sets 2 new and 2 second hand and theyve all died. I have seen a mod to use yaris coils which are almost identical to 1g fe coils which i have spare since the engine swap. These coils have built in ignitors and...

Ah yea, i followed is thread alot while putting mine in. was helpful

Cheers
