The DW800s flow at 800cc, ID1000s at 880cc.

I have the DW800s. 800cc is what I put in with your dead times and I still never could get the start up right. Once it started up though, they ran great.

Look at the ID1000 page: http://www.injectordynamics.com/ID1000.html

The injectors flow just over 900cc/min at 3 bar and 14V (which is the standard test pressure and voltage). 1000 cc/min is comes from higher fuel pressures. In practice we found that 880 cc worked better than 905cc.

Also if you ...

Hondata,

So using a stock map and changing the dead times to what you guys have listed for the 800cc injectors, the car is starting much better. It doesn't take a long time to crank anymore. The only thing that is happening is it seems to dip or bog as soon as it cranks. I have attached a pic and ...

Alright, thanks for all the responses.

It's odd it seems that the RSX ECU lacks a lot of the capabilities of the other Honda ECUs (Si, TSX, etc.)

Thank you very much. Are there any plans to have this be adjustable like S300 and FlashPro or does the ECU not support that?

Hondata,

For KPro, what is the fixed frequency that the boost solenoids operate at? Since we can't change it.

The RSX ECU does not use air temperature compensation for cranking.

I'm disappointed to hear that. I had a little more time to test yesterday and did two datalogs of starting up. One in the early morning where the ambient temp was 73 deg and one a few hours later after the ambient temp rose to ...

Hondata,

I read the help file for tuning starting fuel for FlashPro. It was very informative, however, KPro does not have some of those tables. Tables like "Water Temp Fuel Compensation Cranking","Cranking Wall Deposit Compensation" and what I feel is even more important "cranking air temperature ...

update: problem is back. disregard all that i said. I'm really at a lost....

Sounds good man, I hope it helps as well.

awesome man... i have an ID725cc, and i had an issue when warm start always failed from 2nd attempt, but in the morning it always started in a sec.
I have an 2004 TSX.. i have changed a fuel rail to a skunk2... Tell me, if i understand you correctly the issue was that the fuel line on the rail had ...

disregard.

Hey Spunkster,

Nothing has been done to fuel pump. Everything in the fuel system is stock except for injectors. Stock injectors and startup were fine before I swapped them out.

How do I diagnose leaky injectors?

Probably too much fuel. In the past people with the same symptoms as you have also found leaking fuel pressure regulator diaphragms and/or leaky injectors.

Hmmm, ok. I may get in contact with Deatschwerks again then as these were brand new injectors and still under warranty. When you guys were ...
