It's a ripper of a code for sure. In that link a stuck check valve in the pcv system was the culprit among others...
I distantly remember a faulty neutral position sensor being another...
So I searched that too and got P0607 Throttle Control System Circuit Range/Performance
And then found an lgt with throttle sensor issues...

P0607 relates to high speed canbus

Would be a bad earth I would say. Check the one under dash to ecu. Also check engine bay earths to both left and right chassis rails and the exhaust avcs strap

Thanks Mick. Will clean and tighten the earths this weekend.

Thanks Ben, I had seen the iwsti but tnot the lgt one about throttle control.... been ok this week so far too.

Seems this code has given people so really tricky headaches......hope it skips me!

Installed the best Delkor Silver Calcium battery we could fit in there and voila, no more limp mode

Happy happy

[shav]

wow, amazing you were able to pin point it down to the battery. Great outcome no less.

[Bezzza]

Fingers crossed J!!

When we were reading through the possible solutions we searched, it was like mind field of problems!!!

We will have to catch up soon so you can give the shockworks a spin

Been off for a while, laptop cacked it n been busy with new daughter.

Sooo have exhaust center pipe change to twin 2.25 with 2 x 14 inch x 4inch round magnaflow muffers underway.

Also redoing the front bar, the driveway didn't look that steep...!! Oooops!
Gonna take this opportunity to channel even more air into Heat Exchanger.

Also have an ATP GTX 3576 IW 3inch inlet coming with hoses needed etc to be fitted before Matt arrives early May

Mmmm cant wait!

Mine used to do this until I wacked a bigger turbo in and bam problem solved

Following your advice chook!

[chook]

Haha good stuff mate you won't regret it!

[jslayz]

Went twin exhaust, soooo much quieter but still using straight through mufflers - magnaflow used instead of a resonator in my center pipe now.
Bit of a squeeze but got 2 x 4inch diameter x 14 inch long cylinder mufflers in there.

Much happier with sound !!





Yes I am moving the rear O2 sensor next week too

That actually looks killer. Keen to hear a sound video

Thanks shav.
Its still at the panel beaters getting the custom front bar reworked, I'll post up something after a weeks driving.

Basic check of flow potential:

Twin 2.25 inch center
57mm/2 = 28.5
28.5 x 28.5 x (22/7) = 2553 mm2 cross section area each pipe x 2 = 5106 mm2 total cross section area

3 inch center
76mm/2 = 38
38 x 38 x (22/7) = 4538 mm2 total cross section area

so 5106/4538 = 1.125 = 12.5% more cross sectional area

So with the larger amount of pipe edge to gas which slows flow the additional area should compensate and result in no flow reduction.

What do the forum crew think?

I think the calculations are on the mark, especially for bigger turbo's. Are you expecting a bigger power increase with this setup?

[jslayz]

Only once the 3576 is on there next week

[jslayz]

Finally got around to wrapping headers after the ceramic coat begun to fail.





Tricky job, did a better finish than the first crack at it!
