Pinged him offline. Broke 3rd. Our GCC box with EMCO 3-4 might preclude that failure but still has a glass 1-2, 5-6. We'd like to autocross it.

Our turbo kit is a stage 1, no tuning solution. Avo has a tablet now and will have an EcuTek solution soon.

 

Thanks. At this point, I think the only FI solution I would be willing to chance is a Jackson Racing Rotrex kit. I wish they would say if they are making one or not, because they have had an ND for a good while now.

As much as I want horsepower, I think I will just stick to buying a post-September built '17 and making it mostly a street car with HPDE ability. Make me an oil-cooler kit already!

 

Failure pics of the ND with the revised trans will be coming up soon, too busy with work! Rough plan over here is to attempt retrofitting a 370z trans. Last time I checked, transmission were failing left and right within the Global Cup series. The upgraded gears are supposed to be better along with the studs but quite pricey.

That'swhatI'mtalkingabout!!! Now stick on vents for +5 hp.

But seriously. Sweet ride.

 

Or go lemons style & use it as a bolt on aero penalty.

 

My ND **** the bed. I was driving down the highway to work and I felt a very loud bang and the car immediately started misfiring and every light on the dash lit up and started flashing. I was close to a gas station, so I shut it down and coasted it in. I left it off for a few minutes and restarted it. It ran like complete ****, but it got me to work. I drove it home after work and it has sat for a week now. I called the dealership I bought it from and they said to call Mazda roadside assistance. They are coming to my house after work to tow it to the dealership 100 miles away.

 

oh yikes.

 

Wow. So engine, not transmission eh? Fun.

 

I haven't had time to install the Konis I got in last week. This weekend though... I will be lower.

 

Any update?

 

Mazda roadside sent a flat-bed, so that was nice. The lady at the dealership just called me and they are blaming it on a too full tank of gas. It has a code for misfiring that won't go away, so I am really confused at how a misfire could result from gas... at the back of the car. They are claiming the drain hole just underneath the gas cap getting gas in it will cause misfires.

I have had 6 miatas and I fill them all up to the absolute top of the filler neck damn near every time. I've never had any misfire issues because of that. Not to mention this ND has had 8700 miles of completely full gas tanks with no misfires...

 

So you can break an ND by filling up the gas tank? Interesting.... How long after your last fill up did the issue start?

 

In theory it would be possible to flood it/set rich codes if you filled it up enough it got into the evap system and started to pull fuel through the purge solenoid. Seems highly unlikely to me though.

 

You really shouldn't fill ANY car past the "click" of the gas nozzle. You can slosh gas into the evap system which is not good for anything.

 

umm yeah, while I agree it's not good, I can't imagine it causing a mis-fire, but I know nothing about this new skyactive engine voodoo.

also if it was true I'd imagine them getting like 100+ cars per week for this problem.

 

Lol. I used to brim my Ford truck, wash the windshield, brim it again, wash the back window and brim it again. Evap system and carbon canister held 1.2 gallons.

 

This misfire episode did in fact occur the day after I filled it up with gas, but it had already been driven 15+ miles before it happened. I was also going perfectly straight and I was not accelerating hard at all, so there is no way the fuel was sloshing around or anything.

If I didn't fill the tank past the "click" then my NB would never take more than 7 gallons, even if the fuel gauge is showing lower than E. All three of my NB's have been like that. The ND is my 6th miata and I have never once had a problem like this. Like I said earlier, I have been doing this since the day I got the car and it has been driven much harder with a completely full tank before. I can always get 2-3 gallons more past the click.

 

NBs have some kind of vent issue, there's actually a recall on some 99s for this.

When mine shuts off I start the pump again. If it immediately clicks back off then I consider it done, but if it's happy to add more on auto then I let it continue.

I fill my FXT until the fuel level is visible just above fill tube flapper EVERY time and it adds an extra gallon of capacity compared to what it takes when it hits the first click.
