Hi, to everyone that will open my thread (i'm sure many will not since it is not the first one ).

I read all of the threads with similar problem but neither one of the suggestion does improve the situation.
What i try:
-massive increase/decrease in crank timing map
- different crank timing
-changes in inj firing angle, prime pulse, cool temp corr,post start and base map does not help

I have a VQ35DE stock engine (no mods at all) and Haltech Platinum Pro PNP that simply crank till dead battery. Hot start is good (the crank is little longer then before). With OEM ECU the car start as it should with no problems.

I also send PM to Hal asking some help or base map but he never respond (most probably he stop responding on stupid noobs....... like me ).


In Bulgaria (Eastern Europe) we have no too much tuners, Haltech/Z tuners are exactly ...........zero.

Any help is highly appreciated

Very Best Regards

 

When you say cold starts do you mean on cold mornings or first start of the day?

Post some screen cap of your maps.

Why are you running the haltech on the stock motor instead of a reflash?

 

Interesting ...

im gonna say OP messed up a setting ... I’ll scratch & say injector flow is douched due to fuel pressure variance ...

devil’s in the details...

 

OP's gone.

I tired to answer his other dupe thread last week. MIA since he posted both of these.

 

Hi All,
that is my first thread ever (everyone can check that in my statistic) so CK
take me for someone else.

Regarding the car, does not start on first start of the day (even in hot days).







If some other part are required, please let me know.

Regarding the Haltech on stock car........because I dream about twins in near future, I know it will be hard even painful if gone wrong but have to try.

Thanks to everyone that wiling to help.

Regards
