did IP say you could come back for a full retune since it was never done properly to begin with?

 

i'm not sure. Hal just said i need to bring it back on street tires when i get the housing changed. I was a little upset with the car at the time to care so i wasn't asking very many questions. I hope i don't have to drop any cash because i'm broke as **** now. I probably won't be able to afford the journey and the cost of another tune until next summer if that's the case.

 

DW 600cc

I contacted DW today and received this reply. Thought I'd put it here for reference.


Thank you for contacting us. The latency values we have for those injectors
are below. 7v-17v in 1v increments


3.3
2.6
2.2
2.0
1.8
1.6
1.5
1.4
1.3
1.2
1.1

Thank you. But, there is one value missing. From 6-17 V in 1 V increments should give us a total of 12 values. Only 11 values are listed. I assumed that the value for 17 V was missing when I added these to the DW table in the first post, but perhaps it is the 6 V value that is missing above. Please confirm if you can and I'll update the table if need be.

 

Good spot!

I just got an e-mail back to say that it is 7v to 17v. Last post edited.

 

Here's my DW 600's flow sheet. The latencies are almost identical to 440cc BTW.

 

HKS 1000 cc injectors are exactly 2 ohm resistance across the terminals. I have measured them myself.

EDIT: oops someone already posted this - just noticed it wasn't in the first post...

 

^^^
Thanks to Djamps for the data sheet and to Raj for the reminder on the HKS impedance.

I updated the first post and cleanup of the thread is complete. I attempted to leave in relevant posts that will be helpful to others searching for this information.

 

Does anyone have the info for either of the APS Supplied injectors? The ones that come with the regular kit (440?) and in the extreme fuel system (880?)?

Thanks

 

Here is a spec sheet for the 880cc (650cc) injectors from the APS Extreme kit. I think others who have pushed them will agree that the injectors in no way are 880cc injectors. They scaled out great as 650s for me with the Haltech. Of course, the part numbers were scratched off but I'm confident that they are the injectors shown on the datasheet below.

 

This thread should definitely be a sticky!

are those high impedance RC 750cc injectors in the list the SL4-750 model?

 

Fuel injectors latency chart

 

Here are the sheets for Injector Dynamics.. I was looking for this thread a few days ago. I'm still looking for specs for the PowerEnterprise 380cc injectors that come with the turbonectics kit.

 

A bump for GTR (OEM) 560cc Latencies?

 

better bet would be try over on nagtroc.com for those gtr values

 

Good call, didn't even know about that site, thanks dude. And yup got the info.


They're apparently listed as 560cc but are actually 570cc, and it's 0.890ms @ 13.8 V (14V)

 

per Jared @ uprev
Stock GTR ROM has:
Injector minimum: 1.83ms
Latency 14V offset: 1.78ms (HEX - 59)
Latency slope: -0.18ms (HEX - 5C)

 

Stick to thread... need info about OEM GTR R35 Injector minimum pulsewidth and offset table. Can anybody help?

 

isn't that what i posted?

if not can you please clarify.
