As the weather is warming up I've noticed that my 32gtst is not starting from cold as easily as it does or should compared to winter time, we just had a really cool morning and the car started first crank, when the engine is at operating temp restarting is fine, always first crank, it just has an issues starting first start of the day when ambient temps are over 25c

Any suggestions before I start playing around in nistune?

Probably need more crank prime at warmer areas

After looking at the tables I think you are correct, I've added a couple of percentage in the 20c and 30c blocks of the cold crank enrichment table., have to wait until the ambient tenps warm up to see if it made any difference.

Update: my correction to cold crank enrichment has worked... starts like and idles like a champ once again.

So now I suppose I should start looking for any air leaks, but only when all the rubber is cold.

      That looks good, but I think you're going to need much beefier side skirts now.

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
