hey guys!

just asking for trying to help a friend out!

the car is a 2000 r34 GTT.

ok the car was running fine before it got a service from ultratune. since the service the car on a cold start engine light will come on, slip light turns on, traction control light comes on, it backfires alot and runs really slugish.

we took it back to ultratune they said that my friend has no proof that it was them, what could be wrong with the car?

thanks

Probley better of taking it to a good name tuning shop for service because they will have diagnostics for these sort of things.

Any way could be wrong heat range / fowled plugs but i would say Very GOOD chance that the coil packs are gone.. Nice new set of splitfire coils (one of the best).. This is a very common problem for the R34 Skylines mate.

Good luck hey..

:shudders at thought of a skyline in Ultra Tune workshop:

What did Ultra Tune do exactly?

If it really was running fine before he took it in then it will be one of the things they did.

If not do a search about the problem.

But all the dash lights etc coming on is wierd and would not be caused by coilpacks or anything like that.

no offence femno but umm i do own a r34 and did have this problem and they are the dash lights that come on when there is a ignition problem as most R34 owners would know..

Probley should check up before you comment..

Ultratune... :)

Take it to a decent workshop and get them to look over the car and fix the problem.

You can go see Racepace, RE Customs, Chasers, Status, Le Mans Automotive, just to name a few.

They can help you out.

    • There are a few different ways of doing it. I'm currently running two 1000cc pre-TB nozzles and PWM the pump for control. I'll be moving over to a constant pressure system and direct port. I'll run the pump off a regular relay, have it cycle on roughly 5psi before I start injecting to build pressure and then PWM a WMI solenoid (It's basically an injector that can take a lot of pressure and not corrode with water and meth.) The solenoid feeds the 6 direct port ~200cc nozzles. I'll also keep one ~250cc pre-TB nozzle to help keep IAT's in check.  Safety will be a little different as well. I used to use a pressure switch but will be moving over to a pressure sensor between my solenoid and nozzles. I'll trigger my solenoid and if I don't see specific pressure within a specific timeframe (e.g 100psi within a second, 175psi within 2 seconds), I kill it and revert back to non WMI maps the same way I did it before with 4D in Haltech. I was just figuring out the timers in my ecu last night. They made that a little more complicated than I would have liked... I wish Haltech offered a larger set of logic/math functions like other ecu's do. I can't do very much with just AND's and OR's.  I've been asked to do fuel/ignition mapping on a medium bore engine at work in May (192L V16). Being the only programmer in my region and having went and opened my mouth about knowing the ins and outs of fuel/ignition mapping, I have now been deemed an expert. Fun fun. The entirety of the logic and algorithms are programmed in C on a PLC. As I spend more time figuring it all out, I like what I see and eventually I may consider doing the same as a pet project to replace my ecu.   
    • This would be interesting, would you feed it via a 2nd row of injectors? Or just usual WMI nozzles?
    • Cut sump up and extend. Win win 😂 
    • All, What's the recommended torque for the 1/2 head studs for RB30 twin cam conversion with RB26 head?  
    • also, we need to know which solution worked....
