Hi Jim, yeah ISCV was the first thing I checked. Confirmed it's physically functional, electrically in spec and the 12v supply and harness to the ECU is OK. Got a new ECU on the way in the post to rule that out aswell but don't have high hopes that'll fix it. Had you degreed your 264s all the way to...

OK, that is much more useful information, thanks! I'm not running stock ECU permanently, just using it to run in my freshly built engine and want to ensure everything is running correctly mechanically and electrically first to have a stable platform from which to start tuning with the standalone. (A...

Hi, thanks for your input.

But really I just want somebody who is running 264 cams in a rev 3 engine on stock ECU to tell me if their engine can idle at stock idle rpm, in order to aid my diagnostic process.


Are you running 264 cams in a rev3 with a stock ECU?

Sorry not an MR2, but it is related, and would make a good engine donor for a Mk3. 2002 Toyota Corolla T-Sport VVTLi 190hp (187) Fitted with a Lotus Elise S2 190hp VVTL-I engine and 6 speed close ratio box (from the factory) Around 120k miles. It's a lot of fun to drive, engine has a 2 stage variabl...

Is anybody running a stock rev3 ecu with HKS 264 cams? If so,. Did you set cam timing to the HKS cam card? And with that timing does your car idle ok? Does it stall at all when off throttle I am trying to diagnose why my engine hunts for idle and stalls when off throttle, checked all the usual thing...

there is about 0.4mm difference in major diameter between a 1/8npt and a 1/8bsp thread. I'd suspect one of your fittings is bsp not npt

Do you have photo's of the dump valve? What condition is it in? Any guarantees that it's a genuine one?

Thanks,

Yeah the car is predominantly for track use so I will be either adding a silencer to the current pipe or buying another eventually, but due to a long list of other jobs to do it'll unlikely be done by February

So has anybody had experience of driving an mr2 turbo at Bedford?

Loud pipe? quiet pipe? did or did not have a problem?

I'm looking to book a trackday in February to get some practice in the MR2 before the year begins. Bedford is conveniently close for me but they seem very strict on noise (one strike and you're out). My car currently has a short 3" system with very little baffling so is at the louder end of the...

Yeah that does make sense, I hate searching for vac leaks, guess I'm my head I've been trying to put it off.

Will break out the boost leak tester and rule that out first!

Cheers

My engine is all back together and has done 500 miles of running in, but still won't idle right. Would like to hear other peoples experiences especially where a solution has been found.

Hello fella. If you need these gone, I can collect this weekend. i will take as much as I can fit in my fairly large estate. Don't scrap them, senseless scrapping good parts! Hi, OK, aiming to have it all laid out on Friday and go through it with a mate to see what he wants, then rest will be weigh...

All good condition parts real shame for them to be scrapped!!

Quite possibly. Haven't got that here at home but probably have at least the part that bolts to the body at my unit

I'm having a major clear-out and many of these parts will be weighed in along with the rest of my scrap at the weekend unless somebody wants them ALL PARTS ARE FREE TO COLLECT - But if you want them posting I'll have to charge something as I don't have much time for that.

So from what I can gather from response, the answer to the question is.... The st205 ecu does not have any provision for mr2 power steering. You will lose the idle up (ps pin) and the powersteering cut when engine is not running. But - power steering will still cut at motorway speeds as intended and...

So what is the purpose of the PSCT pin then?

Inspiring build!

Looking forward to seeing this go down santa pod!

Do you have a particular event targeted for its first run?

Hi, yeah ive removed the psct pin and the ps runs, but is there no problem to let it run all the time without having the ecu cut?
