cranking primer pulse width (this is the same as your "Cranking Enrichment IPW Adder Main" table:

This would not be good at all.

 

Jeff,

Try reducing both Cranking Enrichment IPW (I have mine set to 0 at higher coolant levels) and Initial Cranking IPW.

Be careful with the Initial Cranking IPW, if you set it too low the car will not start.

I pretty much got rid of the warm sitting hard starts with my ID1000's with both tables tweaked.

 

Thanks Bryan. I'll give that a shot.

So for the sake of clarity does everyone think its getting too much fuel during warm start?

EDIT: So I just added the Initial Cranking IPW.... I'm nervous about about taking too much out because for some reason my ECUFlash won't connect unless my car is running. If I make a change that prevents startup I'm sort of stuck ..... unless I find someone to help with a clutch dump start.

 

Yes that was my problem.

 

Thanks.

 

Is there a reason why these particular injectors are scaled nearly to their actual size? I have mine scaled at 1008 and both LTFT and STFT are still -8% I'm half tempted to scale them to 1040. I just find that a bit odd.

 

That's normal. I believe they are actually bigger then their advertised rating. Plus I thought the new ones where 1100cc? They don't even list the 1050 high-Z anymore on their site.

Are they these? https://www.evolutionm.net/forums/ec...injectors.html

 

No .... But I wish they were! These are old school normal injectors with 1050 etched on them. But honestly they seem to run stupid rich when scaled to 1008.

I double checked for boost leaks and all is sound.

I have another question as well.... So I've been tuning the IPW and latencies but I haven't touched the bla bla bla vs coolant temp one. Any idea's on how to dial that one in?

 

There are two IPW tables you want to touch for your warm start issues:

cranking primer pulse width (Same as "Cranking Enrichment IPW Adder Main" table.)

Explore changing the two highest temp IPW adder values to 0.


initial cranking ipw

Explore decreasing the two highest temp IPW cranking values. *BE CAREFUL* with these as if you set them too low the car will not start. Take them out gradually.

 

Just throwing this out there as I have been doing ALOT of these lately. Treat the injector like a PTE 1200 and it responds almost exactly the same. It flows A TON more than you would think...or the 1200 is rated higher (likely) than it is.

 

That's a good tip but let me confirm my findings....

Do I leaving cranking IPW and initial cranking maps alone then?

 

If aren't having startup issues then there is no need to. If you are, see my post #160

 

Im doing some major changes.

if I want to say run these on e85 would i try a start figure of 30% less??

Also does anyone have a clue on what latencey values I should try and start with.

I was making 405kw atw b4 just changing to run a evo 8 ecu with telphra mods.

any help would be great.

 

yes 30% less on the injector scaling.

latencies should be pretty close already if you have them tuned for pump.. they might need a tiny modification on e85 (but once you get them working on e85 they will work on pump)
