Re: Cranking fuel tables

Thanks for the help. I have halved the values as my injectors are double the normal size.

40% of 370 = 148
20% of 740 = 148

Kinda makes sense to me.

I will put new plugs in tonight and do a test run

Re: Cranking fuel tables

It is an rb20 ecu from an R32 skyline. Running an rb25 in my R33 skyline.

Deatschwerks injectors are meant to be pretty decent and have factory like spray pattern

I found the cold and warm crank tables, are these it?

Re: Using R32 ecu to tune R33

You designed the Nistune boards didn't you? Ever through of making an add on module for the nistune chip to handle the VCT for the RB20 ecu?

Would probably been a good seller as the RB20ecu seams to be more reliable than the RB20 ecu

Re: Using R32 ecu to tune R33

I did look at them but have not heard of any one using them so I was not prepaired to take the risk.

They might work well and the price is good my MSD one cost $200

Re: RB25det gt35r results

I've kinda got mine running. How do you find the injectors? Do you have any idle issues?

Re: RB25det gt35r results

You have a very similar setup to mine are you able to tell me what latency you are using for your Deatschwerks injectors and the latency voltage change value. I can not for the life on me get these settings correct.

Re: Injector resizing. Rb25det and Deatchwerks 740cc injectors

Interesting. I have long suspected an intake leak, but never found anything even after compressing all the pipe work.
I do how ever think my AFM wiring is dodgy 1 knock and it cuts out. I was going to wait till the injector resize worked before connecting my Z32 but i might just do it now.

Re: Injector resizing. Rb25det and Deatchwerks 740cc injectors

When idling at an afr for 14 - 14.9 the car missfires and runs really rough.

Is this more than likely a tune issue or hardware issue?

If K const and latency are incorrect but its at the correct afr it should still idle smooth? <- this is what makes me think i have faulty injectors

Re: Injector resizing. Rb25det and Deatchwerks 740cc injectors

Matt, Been talking to Deatchwerks over the issue and they have suggested Nissan ECU's report latency incorrectly Stock Rb25 latency is around 570us but on my rb20ecu running rb25 maps the latency says 740us Deatchwerks want me to set latency at around 700us but Ive already done this with the default...

Re: Re-scaling Maf for New Tube Size

Wouldnt you just select a z32 then adjust the K const by that percentage? The curve of the maf wouldnt change just the scaling

Injector resizing. Rb25det and Deatchwerks 740cc injectors

Havin alot off issues resizing my injectors and I am starting to think it is a hardware problem(With the injectors) Did the resize 370cc stock injectors to 758cc(From flow test results) K Const come out to 91 Adjusted latency value to 1300(Flow test shows 1.3ms @14v <- On warmup my car sits at 14v) ...

Re: Speed Desnity??

Isn't that what the fuel map is for?

5psi at 2000rpm use this much fuel
5psi at 5000rpm use this much fuel

All i am suggesting is changing where the load comes from.
