1jzgte issue

[HIZOKU]

Alright im trying to think of the best way to say this

At full load (foot flat to the floor) in 4th and 5th at about 4000rpms - 5000rpms my car hits a wall as such seems like all power just stops for a bit but if i get off the accell and go back on easy the car will go past this no problems

So anyone have any ideas?

Car is a 1jzgte manual with gt3037 turbo and autronic ECU

does it misfire? Are you stilll running stock coil packs?

[HIZOKU]

Does not misfire and running LS1 coilpacks

Why not drive it over to me and I'll have a look and you can look at the poo car??

Cheers Brad.

I will when i have some time

dont worry i have not forgoten about you LOL and car is dirty as today after winton and it hard to find out issue as it only happens at full load in 4th and 5th dont always get to do that and it does not happen with foot is slamed to the floor

you still running an airflow meter?

[JZA70R_92]

1JZGTE uses map sensor not airflow meter I had similar issue ended up being cracked coil packs after some epoxy its all good now!

[HIZOKU]

Alright well i will have to check out the coilpacks then lets hope it is them

lucky im running LS1 coilpacks and they are easy to find

[HIZOKU]

Alright i had a look at the coil packs they seem to be fine from what i can tell

any recomendations on places to go to have them double checked? or other ways i can check them out?

are you getting boost spikes? If the autronic's fuel-cut is set not too far above your max boost, and your wastegate/boost controller isn't great, you might be spiking into fuel cut on full throttle.

Alright i will look into that im using a greddy dual boost controler untill i can get a autronic one so it is all run via the ECU but i will look into this

Well i went to data log on sunday and give it a test run and could not get the issue to happen again so im guessing maybe it was a boost spike issue and not a coil pack issues as it should of happen again

now it was alot cooler sunday but yeah took it for a nice 3 hour drive return trip and could not get it to happen
