well another big day I used it for work yesterday and today, been doing some ign/knock on both runs seems to be going good, next is the WI kit got to find my MAF I had and get it hooked up.

[NickB787]

I will drop this here so I don't fill the other forum I am wondering if it may be real, possible secondary fuel pump failure? going to 20 at @3500 rpm the returning to 10 when off the throttle.. power doesn't seem down though!!', I went back to the last good map before I advanced the ign and when I did a power run it was the same AFR upto 20. Seems sensible

Double check the setting for wideband in the settings tab May of reset it self This can happen when you save the program file into a diffrent place because the run file isn't with it

[NickB787]

no checked that and the information about the wideband is correct.

[NickB787]

Seems to be a problem with the wideband. hope it's not the controller will check it out, put a hold yet again on mapping, really want to get it sorted so I can turn on the water injection and see how much of a difference that will make. would I need to do a fuel learn session again with WI?

[CHILL Gone DUTCH]

Are squirting WI before the Tmap sensor ?? Just thinking out loud, Would of thought the WI would be same fueling just cooling air but if you were spraying after Tmap it might be diffrent story Maybe somone who has used it before might come along and comment

[smiley]

It's not as if he's injecting methanol or anything, as that's a different story.

All the water does, is take temp down, as if it's 10 degrees celcius out there (just an example)

And if the bottle is empty, the ecu still needs to know how to behave.

 

So i see no special learning for WI untill V3 of obdtuner.

Which Wideband controller was that again?

Some have a free-air calibration procedure/button. Or perform such the 1st time after the controller was switched on with no sensor connected to it.

 

Only removing the sensor from the exhaust for this is no fun...

[NickB787]

WI is into the manifold after the. TMAP I had wired into the TMAP but Peter recommended using a MAF which I have and will wire in. The wideband is a PLX unit I got that one because it does not require calibration in the open air.

[NickB787]

got the lambda still to do I installed a LS4 TB today, first start ok, I uploaded the fact it was an LS4 to the ecu on start up when going to drive it I got EML, 999 temp p1514, p1523 just wondering those who have fitted the larger TB any similar issues? hope it's not a dead tb wil start searching when I get time

P1523 throttle position closed P1514 Airflow to TP Sensor Correlation High Did you make the throttle bodie type perminant in the parameters after selecting ls4 i

[CHILL Gone DUTCH]

Sounds like it went back to old type throttle body on second start

[NickB787]

Just checking now almost certain I did, slow tablet

[NickB787]

it saved it so it knows it's an LS4

[CHILL Gone DUTCH]

Have you tried to fire it up again ?

[NickB787]

yep still the same, tomorrow will give the TB connector some electrical cleaner and see

[CHILL Gone DUTCH]

👍 Don't sell your old TB yet

[NickB787]

Wasn't going too need to make certain the be one works and is driveable

[CHILL Gone DUTCH]

Is the wiring the same as 68mm
