hello after reading a few links i was just wandering what sort of power i should expect from a gems ecu my car is a 99 type r with an api rebuild with strengthend rods fmic soobysport full system and decat. my car is due to go soon and the garage is saying around 350bhp is this about right?

 

DOSE ANY ONE HAVE ANY ANSWERS AS I DONT WANT SPEND 1400 QUID PLUS VAT AT THE WRONG PLACE iwas also told that the air mass
sensor is aweak point in the engine. is this right? i brought the car 18months ago with a running fault which turned out to be a faulty sensor
and eventually death of the origanal engine at 45k

 

Hi, Ive got a 98 type r, had a GEMS ECU fitted and mapped by Steve Simpson, also fitted an uprated fuel pump and APS exhaust system, it was dynoed at 330bhp and 330lbs tourque, it went really well for a few months but then went bang but everything else was standered so it was my own fault. I would definatley reccomend it plus Steve is a very nice guy

 

did you have the antilag connected aswell?

 

Also the GEMS does away with the MAF sensor and plums in a air temp sensor on the intercooler instead

 

Yes i had anti lag fitted as well, good fun, but can t use it for too long as does not do the turbo any good

 

since rebuild have you done any other mods?

 

Yea i had Autosportive in Bicester build me one of thier rally spec 2.2 litre engines, very costly but very bullet proof, i ran it for a year and a half without any problems, but ive taken it off the road now as more mods taking place, im fitting an APS SR55 turbo, APS front mount intercooler, Andy Forrest 800cc injectors, parallel fuel rail mod, SX fuel pressure regulator, uprated breather system,GT spec 2 unequal lenth headers and up pipe then ill get steve to re-map it, hoping to see at least 400bhp, its not an everyday car but i would still like some reliability

 

what setting do u normally set your centre diff at as i have always had mine set to completely un locked (can become a handfull in the wet)

 

Have you tried Richard Bulmer for mapping GEMS? Very well respected and a top bloke...

no i have only been to interpro at the moment as he did some really good work on 1996 escort cosworth

 

just been on the site looks good going to ring him 2morrow have you had yours mapped there? if so what type of power did you get from what mods?

 

Yes ,Richard mapped my 93 RA , but its a rally car which has to run a 34mm air intake restrictor in the turbo(so no power made past 5250rpm).
Mods are 440 injectors (matched and balanced), uprated fuel pump,sti5 intercooler, full decat, headers,new coil packs and plugs.
The figures came out at 279bhp and 330lbs/ft torque.

thanx for the info have you won any rallies?

 

Do tractive have their own dyno to map the cars and do they have a good hourly rate?

 

we have had 2nd in class on two occasions...but not any outright wins.

We are up against some serious competition, with people with very large budgets....

All things considered, we do pretty well at the moment...

Richard mapped our car at POWER ENGINEERING on their rollers...

I am not sure what the arrangement is at his premises, because its a fairly new setup.

i will let you know after i have spoken to them. i was quoted 1400 +vat at interpro and that was fitted and mapped with anti lag and launch control they have 4wd rollers and dave is a very experenced persons with the rs brand and ithink they have been doing jap stuff for around 5-10yrs
