take the fuel inlet hose off the engine. turn the car on and see if fuel comes out. also how sure are you there is fuel in the car. i work for racv and you would be supprised by the amount of times we have gone out to a car that the customer thought the fuel pump had died and.the swear they only.just put fuel in it only to get it back to the shop, pull out the pump and find an empty tank. next thing would be to check you afm. im sure someone on here could provide you with the voltages at the plug or if you know some with the same car see if you can borrow it

sorry for the lack of info

soooooo got some tools and done some basic tests..

fuel ok

fuel pressure ok

injector pulse ok

spark ok

even got the injectors flowed and tested just to make sure the wernt blocked

checked to see if the cat had failed and was blocking

problem is still occuring which leads me to belive its an electical problem

any ideas??

if it was the maf it would still run with a lilimt of 2500rpm becoz its in safty mode??

Unplug the afm and start the car. Doubt it's the problem though.

Get a stand alone ecu.

None of this piggy back bs

bingo.

So, the usual advice. Do some research on who are the tuners in your area (you dont want to drive 2hrs + just to drop a car off for tuning of if any troubleshooting is required afterwards) and then work out who is the best and what is their prefferred platform. Of course cost is an issue but you usually get what you pay for and a bad tune = the need for a new motor = prob not worth skimping $200 for the cheaper tuner... In a similar vein, avoid Mine's tuned ECU's. not going into why here.

General consensus is that PowerFC or Z32+nistune is the way to go. Take into account whether having an aftermarket computer puts you in easy defect territory too (if so- nistune)

Hi All,

I'm a noob so I'm not sure if I'm on the right thread or not, but here goes..

Last night I did the mod where you ground out the boost solenoid on an R33GTSt.

Well I read the entire thread on that before attempting it, & then did it as specified.

When I went to test it on my way to work this morning it would not rev over 2500rpm, just kept coughing until i dropped the revs below 2500.

I freaked out (i only just got the car), & put it back to standard, but it still wont rev over 2500rpm..

Have I broken something? Can I fix this?

So far I have reset the ECU as specified (disconnect batt & pump brakes)

I hot wired the solenoid to see if it works (it does)

& I tried running the car with the solenoid grounded & ungrounded.

Still only 2500 rpm..

Please HELP!!!

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
