Thanks Joe.
I thought this might be the case. He is running the newer style auto box too so I cant run the older PCM either.
Ill let him know the news.

Hi all.

I am posting for a mate who is currently trying to convert his 1meg ECU to a cable throttle body.
Can anyone here please tell me if it has been done and if so what is involved?
He is...

Hi all.

I am looking at tackling an LS conversion and I am chasing wiring diagrams for an L76 engine and a 6L80E teans.
Any pinouts or diagrams will be greatly appreciated.

I use the exact same plx. To talk serial with the V2 I modded the PLX and installed a 232 socket and soldered it to the PCB. Pretty easy mod to do. I can take some pics later but my car is in a shop...

Thanks LastCall.
Very helpful indeed. I now understand why there is a dip in the spark table. Im talking about the high octane table also. Currently im getting 8-10 degrees final spark advance after...

Hi Joe.

I disabled B6601. Axle torque limiting.

What would be super helpful would be sound recording software that uses the same time stamp as the laptop time. Same as how EFILIVE does so then you could look back at logs and soumd clips to...

Hi everyone.

Has anyone had a go at building their own knock headset before?
I have read posts in other forums such as this:

Hi again all.

I'm on the prowl for good information again. I have hired a dyno in 2 weeks time and plan on finishing off my VE and Spark tuning. Im 100% confident doing my VE so that is easy and...

I believe I have found my issue.

I have disabled axle torque reduction and I have not had this issue since.

Thanks I will do. Its been doing my head in!

Hi all,

I have been trying to tune my car and found the spark advance was being pulled way down while doing power runs. its being pulled so far down there is a noticeable slump in the power then...

The only change I have made since your last tune fixed my limiter and gear hold issue is that I have increased my boost from 8PSI to 12PSI.

I also notice when in first gear and going walking pace...

Hi TAZ,

Just wondering if you can please help me out again?

I am doing some tuning on the LS1 and it appears the gearbox is slipping. If you have a look at Log_0011 I have attached at 13:40:26...

TAZ your a true gentleman!
Thankyou for your help with the first gear hold. It works an absolute treat. At WOT it holds gear until the limiter! Now I need to stop it spinning the wheels! Haha.
...

Thanks Taz.

Ill give the tune a shot tomorrow.
Had the tune I been running set up as a 4l80? I didn't think that would be possible?
I am confident the speed calibration is accurate as I have...

I have just stumbled across this thread.

If I set D0913 to 0km/h will this mean that the PCM will not command an upshift 1>2 when holding D1 unless I upshift to D2?
I have noted in my tune D0919...

Hi Joe.

I looked at that earlier after doing a search on the forum. D0913 is set at 88kmh already. My car is shifting at 45kmh odd. I had ignored this parameter as I thought this wouldnt be the...

Hi taz.

Yeah its a 31" tire and 4.11 lsd. Your right about the gear position switch also. All stock and wired to the pcm.

Why do you ask mate?

Thanks.

Hi all.

I am trying to sort out an issue I am having with my 4L60E.

As the title mentions I have the shifter set on 1st and do a power run (drag run) but the car will automatically shift to 2nd...

Bit of feedback for you all.
The knock when coming on boost was due to gear shifts. Bogus knock!
We have got the PE working correctly thanks to joecar. Until you mentioned we werent aware the tune...

Thanks Taz.
Ill give it a shot over the next few days. Ill do a compare anyway but what have you changed in the tune?

Cheers

Here is the current tune.

Hi all.
We are currently tuning a car with a 4l80e installed and when doing power runs the box will automatically shift from 1-2 and 2-3 when the shifter is holding gear. Is there a way to stop...

Cheers joecar.
I think my PLX must be the latest generation maybe v3? Mine has a lot different pcb installed but either way I got it going. I used some info off that thread in regards to the TX and...
