Its cutting out in higher rpms!!!
 

While Im driving my turbo b16 it starts to cut out at higher rpms. I put it a 255 walboro,new fuel filter, check valves and still does it. anyone have any ideas of what it could be? In higher rpms I mean it barely lets me go 1/4 throttle after around 5k it might be after vtec kicks in. any help would be great.

come on someone's gotta know. first person to get my prob solved I will send them 50bucks via paypal as soon as I gte paid. :y

Re: Its cutting out in higher rpms!!!
 

Im havin the same damn problem.....
it feels like it runs outta gas or the timing belt broke then....just kicks back on
and im goin again....with the same steup as you running 5 psi....

I cant figure it out..

Re: Its cutting out in higher rpms!!!
 

Mine runs awesome if the charge pipe blows off lol it will pull all the way to 8.5k. cause it has no boost. As I gas mine it sputters and doesnt let the rpms go up hardley any but they go and and I try to floor it more then the car bogs and tries to die but if I let off everything is fine.

does anyone have any clue?

Re: Its cutting out in higher rpms!!!
 

Why put time/money into a turbo b16 only to slap an FMU on it? >:(

Re: Its cutting out in higher rpms!!!
 

I talked about it in one of my previous threads. Im only using this fmu until I get things working right then im getting all the stuff to tune via laptop in my car. Im waiting for xeno to get back to me on how much it was gonna cost for what I needed done.

TPS short/broken?
Check the injector duty cycle, noid light.

Re: Its cutting out in higher rpms!!!
 

How do I check the injector duty cycle? Im not familiar with that. sorry if thats a stupid ?. but yea my TPS is broke but its still plugged in and all. It runs fine with the charge pipe off in no boost. so it only acts up in higher rpms with boost.

Re: Its cutting out in higher rpms!!!
 

how much boost ?? how many check valves? throughing any codes ??
try switchin your two outter tps wires around

Re: Its cutting out in higher rpms!!!
 

Im running 8psi, I have 2 check valves, and no Im throwing any codes beside IAT sensor is umplugged. Ill try the switchin the two wires around on the tps tomorrow. But its fine when I drive N/A so could it still be that?

Re: Its cutting out in higher rpms!!!
 

A new dizzy cap and rotor solved my problem.

Re: Its cutting out in higher rpms!!!
 

sorry I forgot to mention. I changed cap and rotor already.

Re: Its cutting out in higher rpms!!!
 

try 3 check valves silly :1

Re: Its cutting out in higher rpms!!!
 

Ill try that later today too

Re: Its cutting out in higher rpms!!!
 

I'd make sure all other problems are fixed first so you know you're not throwing any CEL's. Go out, test, and see if you do though. You could be experiencing an ECU limp mode possibly.

Another check valve may solve the trick. :S

Re: Its cutting out in higher rpms!!!
 

yeah i changed my cap rotor and fuel filter today and it works great!

Re: Its cutting out in higher rpms!!!
 

what size fmu are you using turbozexcrxman? I know what limp mode feels like its not that. its way diff.

Re: Its cutting out in higher rpms!!!
 

Oh! come to think about it. does it matter that I have an LS dizzy on my b16 with one the arms grinded off?


I just ordered all the stuff I needed to do datalogging and chip my ecu to tune my car. SO NO MORE BITCHING ABOUT IT.! :P

Re: Its cutting out in higher rpms!!!
 

it prolly matters seeing that vtec dizzys are differnt ditch the fmu!!!!!!!!!! youll be glad you did

Re: Its cutting out in higher rpms!!!
 

Yea I am, I ordered the stuff. and selling my vafc for 50shipped.

Re: Its cutting out in higher rpms!!!
 

Yeah, I'm waiting to ditch my FMU too. Only problem is finding a manual tranny for the f22b. I know a guy in town who has one, but wants way too much.

I'm sure once you tune it and ----, the bitch will be right.

Re: Its cutting out in higher rpms!!!
 

well my car started ------- up again today....its really starting to piss me off

today im going to check the connections at the pump...and at the main realy.....

iT might be the injectors.....iunno though.....im just pissed cause almost everything is brand new...non remaufactured ----
and i cant enjoy the ------- thing

Re: Its cutting out in higher rpms!!!
 

Yea I feel you, Ive been buying everything that I need brandnew so I wont have any probs also. I called a guy in arlington who owns and import shop and does alot of work on hondas and acura's, well he said its leaning out in vtec, from what he say's it needs alot more fuel when vtec engages and its not giving the right amount of fuel with only the fmu. So I figured I should just go ahead and order the ---- and do it right so I can drive it already.

Re: Its cutting out in higher rpms!!!
 

my fmu fucked my injectors

Re: Its cutting out in higher rpms!!!
 

Yea I think my injectors are maxing out. But ohwell I have everything coming in to tune it with. Are there any popular tuners around texas area with dyno or however they wanna tune it? I can drive a lil ways too so it wont be no probs with that. if there are let me know how much you would charge me and I will get the money if I have to work 140hours at work again lol.

Re: Its cutting out in higher rpms!!!
 

I replaced the entired dizzy with a new one and it works great....the brushes inside were all torn and ----......

I checked my Fuel pressure....at idle im running 75psi
in boost it jump to 85psi..and holds steady.....

Does anyone have or know any places the i can get a diagram on were the fuel lines run?
I want to replace them with some bigger steel braded kind....

Re: Its cutting out in higher rpms!!!
 

what size injectors are you using? if your on the stock 240's thats part of what your problem is.

Re: Its cutting out in higher rpms!!!
 

Yea Im using the stock 240's from an LS. But Im about to be using my 450's

Re: Its cutting out in higher rpms!!!
 

ding ding ding thats your problem.
