Hot start

Hi i am running a haltech platinum pro on my r32 gtr and i cant get it to start ones its above 40c i am running e85 and 2000cc injectors

It will only start after cranking for a while and keep pressing the throttle pedal open

Have you tried making changes to your cranking enrichment table? It could be that you need to increase or decrease the values in this table so you may need to go both ways and see what works. Start with a large change like doubling/halving the numbers and see what it does before refining your adjustments.

Normally the issue with E85 is cold start performance so you shouldn't have too much difficulty at 40 C.
