Got the FMIC and hard pipe kit fitted
Ive had 2 small problems with the car. one was that between 5-7k ish under full acceleration, it was overfuelling like a bitch, spitting flames out the back and not really accelerating all that much (almost like one of the cylinders wasnt firing), the other was that it would completely lose power (engine power, not electrical power) for about 1/2 a second and then just carry on as normal, but it very rarely did that.
Today I replaced all the spark plugs, cleaned the coil packs, put WD40 on the connectors and then took it out for a spin. Fuelling problem seems to be 100% fixed now, accelerates all the way through the rev range with no hesitation, however the intermittant cutting out has become more frequent. Any ideas?!
Aside from that, im loving the car  Got far too many plans going through my head which I know I cant afford  Tuners that fitted the FMIC said they found some oil in the dump valve so it may be a sign the turbo is on the way out, so ive already been lookin at replacements and upgrades, also an Apexi Power FC ECU. hmmmm. God damnit, and I said I was gonna leave this one standard

get it mapped and setup to get the most of the cooler and running correctly..
now its got the cooler it will feel laggy and less powerful untill its running the correct boost to fill the cooler.. does it feel like the above?
what boost are you running?

TBH its hard to tell, cos I only got the FMIC fitted on friday, and I did the spark plugs today so now that its accelerating all through the revs, I prob wouldnt notice if it felt a little bit slower in gear. AFAIK its standard boost, but it has an HKS actuator too so I need to get a decent aftermarket boost gauge and find out really.
I think plans are now (apart from saving up first ), 550cc injectors, up boost on standard turbo and a new ECU, then after that get a bigger turbo and map it again for that. I know it would be ideal to do it together, but its a question of money

Does it have HT leads? if so prob worth a change to try and sort your mis firing.

yer, plans sound cool..
after doing a little bit now and then, find a decent tuning place near you can get them to check it over i mean because if it starts running lean on a piston (does happen) then it wont be cheap..
my mates 1.8zvh turbo ka was running better then ever, untill it blew a piston (same piston it blew with the cvh turbo engine he had fitted before) all down to the ecu not fueling one cylinder correctly again..
just saying for the sake of £90/100 for a fine tune it may be worth it and can assure your the fine tunes make soo much difference to how the feel/drive

Nope, each cylinder has its own splitfire coil. I bought some ultrasonically cleaned stock injectors too, so I may look into fitting them myself if I feel comfortable doing it, otherwise it may be going back to another garage after xmas lol

May be worth checking boost pressures.. they have a fuel cut on them when they boost over 1.0 bar

Why are GTR's so difficult to see in Spain?
Love the car.
Donde están mis pegatinas, cabronazo?

I hit the fuel cut on my classic loads when going for it. Over-boosting for some reason. Never bothered fixing it. Only did it when I was REALLY going for it....like a split second of no power and you'd lean forward a bit

The only things that have changed are the FMIC (and driving back from cardiff to hereford, I didnt notice this new problem) and the new spark plugs. Any idea what might be causing it? Are performance spark plugs a must? I got some from the local motor factors using the same part number as the ones I removed, but they arent iridium tipped. I tried everywhere in town and thats all I could find, and I didnt want to drive to cardiff and back with the car overfuelling as much as it was in case it did some damage, so i ended up fitting those spark plugs instead of iridium ones.

Standard boost gauge is reading just under 700mmHg, but dont know how accurate that is. Ive just bought a blitz Mirror Drive boost gauge as a christmas present to myself though
