It has just been suggested to me that there are issues with standard ECU / tune if you decat the front pipe or put a high flow cat in with new front pipe. As there are no more sensors after the one in the dump pipe this seems like bollocks to me and have not read anything about this anywhere on these forums.

So can some one with stock ECU, custom dump and decat or highflow in front pipe just confirm there are no issue with how it runs on a stock ecu.

Thanks :/

It is funny how ofter we hear people being told porkys about the M35.

I had stock turbo, stock ECU and special dump pipe and 3inch exhaust from the dump back with high flow cat.

And the car runs beautifully. It won't make the car any more economical but you will gain some more power and pick up.

Cheers

Dump pipe, high flow cat & aftermarket exhaust. Absolutely no issues, more power,, more torque, no downside.

Someone is talking out their ear.

Thanks - probably the other end of their torso talking. :/

whats a cat?? :(

i know the sensor he was talking about. it existed on early 90s jap imports and it was a temp sensor for the cat. maybe if he actually looked at an M35 he would know. most people just throw imports in the same boat, mostly along with C34s hahah

I wonder why that would happen, lol!

100% no issues.

I have a high flow, a custom dump pipe, had a Kakimoto 80mm de-cat front pipe and a Legalis cat-back.

No issues whatsoever.

Indeed... whether it is the engine, transmission, DVD "player", suspension or exhaust, there are very, very few sellers and workshops that get their shit right with these cars.

Hmm... maybe someone needs to put a website together where people could easily get the right info on these cars....

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Looking for a part number for this part here

      By dbm7 · Posted

      Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
