My lambda is all over the spot, no smooth idle. i have attached my map before changes and log.

the engine is a 2JZ-GTE none vvti with HKS 272 cams.

a mate took a look and noticed my ignition is offset by 2 for some reason, not aligned to the injection order, we aligned these then the car just failed to start completely.

im a complete novice and know there's a few other things not right on my map.

would someone with a little more knowledge be able to take a look and let me know what you think

Hello have you set the base timing it appears to have very low manifold vacuum for those cams and ignition timing. what id the fuel pressure set at and it it stable

Regards Ross

Hi Ross,

i used similar timing to a mate, i haven't yet had a chance to test it.

The fuel pressure should be around 53psi however my sensor is throwing 108psi at me. i am going to try re-calibrating it and go from there.

i made a few changes and the car seems to idle stable now however that is at around 0.7 lambda and with the ignition still offest by 2. i am planning on taking it for a test drive this weekend or next so i can get a good log of what is going on.

does the offset ignition seem odd to you?

Quickly looked at your map and compared to the base map that ECU Master have, and it seems like your injector phase parameter is not adjusted properly. I have attached a picture of both table to compare. Maybe that will help!

As for the ignition output being offset by 2, looks like it's the same in the base map. I will also attach this said base map.

Disclaimer : I am no 2JZ guru :)

Cheers Frank. i will make those adjustments and see how it goes.

The high fuel pressure signal can throw off the fueling as the ecu takes the fuel pressure into consideration I believe.

Literally today I was starting on a new calibration on an EMU Black and I had the analog inputs for the fuel pressure and the oil pressure crossed up so the fuel pressure reading was incorrect which threw my injector pulsewidth for a loop. Especially on startup. Just something to consider
