I understand this setting ajusts fuel enrichment on starting ?

What settings do you use ? Especially interested in knowing from those of you with bigger injectors.

Reason I am asking is, I find that my car is hard to start when it is hot or has been running for a while.

Cold start is fine - it kicks over first pop - no worries - even from dead cold.

But when hot - it takes maybe 3-4 good cranks before it will start. Sometimes I have to leave it for a while.

I guess it might be coil packs or fuel pump - but I doubt it - cause the only thing I have changed recently is the the PFC (replaced from Microtech where it was starting fine)

Any other suggestions ?

Cheers,

Brendan,

My car does the EXACT same thing... Perfect from dead cold, perfect if I start it up again within a few minutes when hot, but if I leave it for a while when hot, it takes 3-4 long cranks to fire up.

I thought it was my Bosch 044 fuel pump, but I dunno anymore... I really need to give Paul (Stace's pit bitch) a call, he said he went through the same troubles with Stace's car, but I haven't gotten around to calling him yet :looney:

Possible factors:

Power FC Pro

GReddy 800cc injectors

Mines AFMs?

Bosch 044 Fuel Pump

Makes it hard because I had so many things changed at once, troubleshooting is going to be a biatch :D

I had a look at the Cranking table... Interesting that you can't adjust spark timing, but only injector width?

And what do you reckon the temperature is? Water temp?

I'm gonna become me a car tuner :rofl:

hi guys

we run 4.0ms at 80deg and 7.0ms at 50deg, if thats any help. 720cc injectors are used, but staceys cranking prob was pump feed voltage drop. Merli if any probs call me if you want to discuss further.Paul.....DIRTgarage

Do you mean ignition timimg ?? Cause you can on the timing map - 1st set point is 400 RPM.

Unless you mean something else ??

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...

      Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.

      Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?

      Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
