Hi guys I'm looking for a way to tune my s1 stagea

It's currently running a garret 2871r and 3 inch exhaust but before putting it on a dyno I would like to fit bigger injectors and a z32 afm to maximise the potential of the turbo.

I would like to know if anyone has heard of using a rb20 gts4 auto ecu and installing a nistune board to tune a stagea?

I used this method to nistune an old r33 but am unsure if the gts4 ecu will play around with the 4wd system in the stagea.

I would think its not the awd but the auto you have to worry about. The Attessa has a seperate ecu but the S1 stagea ecu contains the auto ecu - don't know what the story is with the R32GTS4. Your best bet may be to piggy-back an E-manage ecu.

I've spoken with my tuner this morning who works alongside the development of nistune and he's going to talk with them and find out if it's possible. I wonder if the transmissions are much different between the 32 and stagea.

Pretty sure you just need the R32 gtst ecu from an AUTO.

Nistune that board.

Then the hard part is rewiring the 3-lines of pinouts of the S1 to the 2-lines of pinouts to the R32.

Keep in mind that there are wiring differences in S1 ecu's.......

I bought a wiring loom already done with a 32 ecu. It started ran and drove but was too lumpy for my mods. Double checked the wiring and everything looked fine, but i had my doubts because the way it was wired didn't make sense to me. But I tried it in good faith.

It should never have been sold to anyone and should have been thrown away

Took it to get tuned and he said he would check the wiring too but once on the dyno it melted 6 coilpacks. Took it home and cut all the wires and marked them and triple checked the wiring. It all went to where it should. But still didn't make sense on why it was wired like it was (really messy) ((like really messy))

I wouldn't bother with a nistune and I'd go a brand new piggy back.

If you really want you can have the ecu and wiring loom for 100. I was going to throw it away and sell the ecu for 100.

Very well explained....as I was going to think bout nistune as well till this happened

    • 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 
    • I like this page, better than that silly turbo kit   https://v8roadsters.com/product-category/engine-conversions/engine-conversion-lsx/engine-conversion-lsx-nc/  
    • That would be my Shoei helmet
