So, i found a Midlands tuner, Greg at Protuner with good feedback and eventually managed to book him to tune the R.
Due to his workload i waited 2 months but then on the day, due to personal reasons he cancels! Fair enough, these things happen, but my R still hasnt been professionally looked at since i rebuilt it.  Mad  Mad


Anyway, i want to stick with the stock ECU so theres no remapping, so how hard can it be to tune it?  Suspect

A few facts first;
It has an Apexi boost controler, CP forged pistons, quaife box, ACL race bearings and mechanically runs fine, in fact ive clocked up 2000miles now.
The only tuning i did was set the timing at 20deg tdc after rebuild.
Last month Mike adjusted the Apexi and lowered the boost to .7

So can anyone tell me some basic steps i could take to achieve maybe 300 from it?  study
Right now it feels like im only getting about 200 from it.  Embarassed  Embarassed

Timing; is 20 tdc right?
Fueling; how do i adjust this?
Apexi; what should i adjust this to?
How do i check for boost leaks?
How do i check vac leaks?

Or better still, can anyone in the midlands do this?

You should get 300 easily enough. 2.75 or 3" turbo elbow and similar size exhaust helps drastically, healthy turbo or something like gt2860rs or gtx2863r handles mid to above 300s .
Only thing you can do with fueling is fit a sard pressure regulator which gives some ability add more fuel to boost which can be handy.
If everything in good shape 300 to 330+ is achievable, with your engine and box you should look towards 400 range in future perhaps . Piggybacks are still worth concidering. I had good results with late model unichips before full mapable ECU's became common practice.
Really need get on rollers just see how fueling and ignition looks and if all good wind up boost a bit and see what nets you .

Sorry to jump on this Neil, so the std ecu can't be mapped? Bugger I thought it could, doh. What replacement ecu would be recommended?

I'm not 100% sure tbh, but thats what ive heard.
Ive also heard you have to fit 'daughter' boards ontop of stock ecu if you want a remap. Question

Standard cant be mapped the nistune is a daughter board which is added. You can use things like apexi safc2 for cheap piggyback like Spike uses to power fc nistune and other stand alone ecus which are more expensive still

Neil its hard to say, mine is stock ecu injectors and afm and as its rebuilt is has JE 87mm pistons cosworth hg hks 264 cams arp rod bolts stock crank and acl bearings and it feels flat on stock boost. Problem is small changes can make some difference such as front mount cooler and other bits. Have you had your injectors cleaned? Really its hard to say without getting the afrs checked and things like that generally you have gone through most things now.

Thats just it; 'rollers'
They're rarer then rocking horse shit round here and even if there was, they wouldn't be an R specialist.
Ive got no chance, which is the reason for my post.
I have to check the fueling ignition myself so just need some basic tips to get the most out the engine, but staying safe.

Hey Shroom,
Injectors where exchanged for refurbbed ones by Bob,
Ive a fmi too.
My R feels flat, makes the right noises, generates the boost but doesnt seem to yank my neck back.

Yeah thats what mine is like too, I have had 6 Pulsars ranging from stock to just under 400bhp so know what they can be like but she is flat! Going to get mine sorted down at Bobs once I have sorted the turbo

Bob was my first port of call but he had too much on.
Might give him a tinkle again.

Yeah im not in too much of a rush so was going to get some bits done then see if he can squeeze me in. I think you have covered most of the basics really as you have fresh injectors, clean afm, decent leads and dizzy etc only thing I can think is your aftermarket fuel regulator is not setup right bogging the car down along with the addition of the front mount, exhaust system, forged pistons has all altered it so the stock ecu is not working very efficiently. As said im just guessing really and have no practical knowledge so it will be interesting to see how our paths go to sorting it! It would make sense as if you did any mods to a scooby they soon go off the boil

Now you have some miles on the engine Neil and things are bedded in it would be a fairly simple job to work out what the issue is on a dyno.
Could be one of a few things causing it to be flat and gutless but sure we could have it done in a day for you without any dramas and not gonna cost you an arm and leg.
Certainly do not need mapping or aftermarket ecu to reach that power.
It comes down to afr as to how much boost you can run and as long as knock levels are within limits which they will be if fuelling is good then there is no reason why you should not be able to run in excess of 1bar which is circa 280-300bhp. We've done this many times now and many cars have been used on circuit and are still going strong.

Give me a bell fella as should be able to get you in before the Mallory trackday as you will need to make sure things are spot on before venturing on circuit with car

As mentioned in another post a wideband afm is a super useful gauge . Trip to Bob would be good plus he got lot of spares which means most things can be tested/sorted same day which handy .
On subject of ecu mapping, piggyback is underestimated & easier tune than old style daughterboards, it cost effective on more basic mods and power goals and easily reverted to stock .

This is all over my head tbh and i certainly dont have the kit, the skills or experience to do it.
Luckily there's a man in Essex who does,
Thanks for getting back to me Bob,
