Goes lean once it reaches operating temp, car dies.

Ive got a buddy with a car that has had all kinds of misc issues. RB20det swapped schassis car with 11u0f for RB25 so that we can use the TPS idle trigger instead of his rb20det TPS. He is running the popular chinese fabricated front facing manifold that companies like Zerofab sell. We have actually...

Re: Rb25det Hcr32 idle issue

I got the initial issue fixed. Now the fuel pump is doing some weird surging at idle. I crawled under the car and the feed line is actually pressurizing and slightly depressurizing at idle. The fuel pump control module controls this, correct? I am not intimate with this platform on that level so Im ...

Re: Rb25det Hcr32 idle issue

I always thought the worst of it was that the spray pattern was garbage?

I'm going to just look for a stock set or go with top feed.

Re: Rb25det Hcr32 idle issue

I went full retard: the intake tube fell off the MAF.

Idle is still a little rough though. I think the injectors I have are stock "high flowed" side feed injectors... you guys ever dealt with these?

Rb25det Hcr32 idle issue

Has 720cc injectors and Z32 maf. I fixed idle tps trigger and set the injectors + MAF in Nistune. Engine won't idle without injection multiplier up around 500-600 from the 150 or so that it is sweet to after initial adjustments. Once I got it running, it will abruptly die after it's running for 15-2...

Nissan crowd obsessed with Speed Density/MAP based tuning

I cant even count how many times Ive gotten into arguments with people over MAP vs MAF. Usually people start spitting out a lot of bro-science about MAP tuning when, realistically, they have no idea what they are talking about. I know there are a number of high HP cars that run speed density but, as...

EDIT: Fixed!

Set the TPS voltage and then tuned in his idle/low load fueling. Running good.

No problems doing this of they plan on going rb25 in the future right?

If so, should I just copy all rb20 maps over? Any other changes?

Re: Building your own knock sensor headphones

Matt, what do you think about connecting two microphones? Putting one near the front of the engine and one near the back. I FINALLY got all my stuff I ordered from Jaycar (I dont know why it took so long) but Im going to be assembling it soon. There was a minimum order amount so I bought two microph...

Re: No ignition on cylinder 4. Burnt up resistor in ECU...

Fixed it. The RB26 ECU and RB20 ECU had different ignition components inside but apparently they are compatible with each other. Went through about 3 spare coils and two igniters trying to figure out what was wrong before I tracked down the grounded out wire. Then replaced the resistor and the board...

Re: No ignition on cylinder 4. Burnt up resistor in ECU...

Ill see if I can replace it. Ive got a bad GTR ECU and the GTS-T ECU I am trying to repair... worst case scenario is that I still have to buy an ECU.

Re: No ignition on cylinder 4. Burnt up resistor in ECU...

Would there be any visible burning/damage?

I assume it is the larger of the two orange boards? Any chance just replacing the resistor will work out fine?

Either way, I have an RB26DETT ECU that I may be able to swap parts from if they are the same. I am going to check tomorrow.
