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!!!

    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
