alright guys im back and i got a question.

[rb25drag]

I work for Adman electric, We get off at 3:15, rain or shine, So just give me a call I would come by tom or friday but im getting mine ready for the track Friday night.

Just give me a call anytime, Im working mon - friday there.

We can figure it out. I think i have been through it all LOL.

The 2 tools I use the most on mine is the Wideband 02, I really recommend that, It is your #1 tuning tool. also the SAFC is another you can tune with, its difficult, but the wideband makes it alot easier. Its just a cheap tool until you can buy the good stuff, But if your like me, Poor/Broke, its hard.

When you guys find out whats wrong post on the board so I can try it on mine please

[leesredgt]

ok will do.

[leesredgt]

will bumping the timing up to 20* with out a wideband hurt it, i just thought about it.

[rb25drag]

No, you should still be fine at 20*

You definitely have a fuel problem. Your plugs are not the problem. The plugs are probably fouling, which is why it felt better when you changed them, until they fouled again.

First things first, check your maf wiring and maf. Maf wiring must done using shielded wiring. If you have the power wire running next to unshielded signal wires you are gonna get interference, and the car will not drive correctly. If the wiring is 100% try and clean out the maf with some maf cleaner.

Second if you have the stock fuel pump, replace it with a higher flowing pump, and get a fpr to adjust for proper fuel pressure.

Also don't mess with the tps, its not the problem.

thats what im thinkin, its the fuel.my maf is good i checked it and i had my harness done by someone else so i know its good. i have a walbro pump and a nismo fpr.My fpr is set to 36psi with the vacuum line"ON". I dont know if that is correct or not i though it was.

I figured out my problem it was a malfunctioning MAF would work some time and not others. Have you downloaded the FSM? It has step by step instructions. Have you checked the MAF with a hot and ground from a 12 volt source on 2 pins and a multimeter on the other two wile you blow air through it?

[leesredgt]

yeah ive checked my maf i might recheck it though.

man it seems like tons of people have this problem with the rb25?? are all these people just doing something wrong or is it an rb25 thing or what??!?!?

Keep in mind, for every person you see that has these type of problems there are 20 that don't. I would say all those people are doing something wrong LOL. I know I created the majority of my problems at first.

Don't rely on that fact. I'm damn good at wiring and even i've f'ed up and made mistakes. It only take one little solder spike to poke out through the heatshrink to cause problems. Just unravel the area they spliced wires (Will be fatter than other areas). Also double check they used shielded wiring for the signal wires

Your fuel should be ok with that setup...

ok i tried bumpming up my timing, and well.... i hook it up and it showed 10* and i know for a fact i set it to 15* so aparently i pulled timing so then i try bumping it up it went the opposite direction to 5*(i turned it counter clockwise) so i turned it the oposite directiojn and now its a 0* so i turned it back and it didnt move so i just visualy centered it back up and tightened it down and left it, its to hot outside to work on it right now.

[leesredgt]

ok i checked my maf and everything seems to be ok and intact.

[rb25drag]

So does it still Spudder?

[leesredgt]

i didnt get to drive it b/c it wet out.

[leesredgt]
