Beats me - its the 88590015 rom, Mrfred was the one who discovered the tables so he would be able to answer that better than me.

So when you zero out your IPW map your car will not start - just cranks but no fire?

 

Yes if it's cold out and the car is cold, it will not start with that zero'd out on E85.

Warm start on E85 will start but takes longer.

Currently on my personal car, I have them dialed in on RC1000's, starts up right when you turn the key in all weather. Slight hesitation to start in 15-30F in Tahoe. Mini-battery and all.

 

Wait your running rc1000's or dialed in as them? Would you care to show some latency settings im just curious how they look.

Would a bigger latency on the really low voltages affect startup? Because say on PTE 1200's the 4v latency is 5 i believe and on rc1000's is 3...

 

It could, log your voltage when cranking.

Yes my personal Evo is running RC1kcc's.

 

It looks like its about 4-6 v's. When you say log it, do you mean before i turn the key over or while its cranking?

Also if i understand right and this only applies to warm starts. If having the pedal to the floor makes the car start faster then its because there is too much cranking fuel from a too big of cranking IPW adder and if it doesn't then the IPW adder isn't big enough.

I increased it to 14 ms for the 50-82C range and that seemed to aid in helping the car start faster with no gas.

Also here are my current latency's.
3.312
2.184
1.56
0.936
0.696
0.384
0.288

Here are the ones im thinking of trying to see if those make any difference.
5.280

Thanks for the help

 

Why is it that I can't find a IPWxCoolant Temp in Ecuflash?

 

Has anyone been logging (hot) starts? I noticed, and it doesn't always do this, my coolant temp will be around 190F, and during cranking it shoots up to 320ishF. It falls back down to 190F after it's started. Then, I'm assuming because of this, the calc load shoots up to ridiculous numbers like 400+ even 2000+ for a couple frames. This in turn makes the AFR map around 37AFR and throws 38 counts of knock for those frames.

I can post up a little log if anyone wants to see this.

My problem is warm/hot starts. Warm starts are horrible and hot starts just aren't satisfactory. I adjusted the table in this thread but the idle acted weird and I had really bad throttle hang issues. So I'm back to the stock settings for now.

I recently played for a short time the start enrichment table and it seemed to get rid of most of the crazy evoscan numbers (load/coolant temp/AFR map). It still doesn't start nearly as well as I would like. Is there a target AFR I should be trying to hit during starting?

 

So has anyone found a fix? I will pay someone to help me fix it........

My car starts just fine now after modifying the IPW for starting. If your adjusting it and nothing changes it probably isn't the right table.

 

I tried adding timing to the starting area and that seemed to help. Although when I logged it, it has 5 degrees of timing for a little bit and then kicks into the table. No matter the adjustment it always starts at 5 for a bit. I think a degree or 2 might help, is there a table for cranking timing?

 

Did you have to increase or decrease the IPW values to improve warm starts? And at which coolant temp ranges did the changes seem to have the most effect?

 

Bump to see what changes seem to improve warm starts. Better yet, anyone who has improved their warm starts want to post their "Cranking Enrichment IPW Adder" table?

 

Posting that table won't necessarily help you, since it is dependent on the injector size and latency. But, it will give a good idea of the adjustments that you may need.

 

+1 for IPW settings


and any idea for the timing table?
