As above, I am chasing details on injector size used in Cosworth Kit for NC model MX5 .

Also what map sensor is used for tuning.

Cheers Novice1

PM Sailor (Rob), he has one and can give you all the info you want.

the cosworth kit comes with the upgraded injectors.

Let me get this straight, 3 tuners in a row have tried to tune it without knowing what map sensor, or what injectors it has? With the history of s/c NCs I'm not that surprised but 3 in a bloody row?!

Ok for clarification.

Original tune by Flyin Miata 118kw atw , drove nicely, but power well down on what expected.
Flyin Miata believe causes of power loss, I quote "Most common causes of lack of power would be bad catalysts or possibly the bypass valve on the super fouling on the brake lines on the firewall. Cats would be especially indicated if the car initially ran well".

Second tune from an Oz ecutek dealer, don,t know name or location. First reflash 190 hp , quoting my mechanic too lean, drives loke a dog.
Second reflash from oz ecutek dealer 170 hp again drives like a dog.

I asked Bullet cars who contact flyin miata re what injectors were used and what map sensor.

Reply from Flyin Miata , injectors and map sensor standard ones that come with the kit. Talk about not really telling you anything, LOL. Mike Mann says injectors that come standard with kit are Blue Tops. As to the map sensor still in the dark. I have asked Mike Mann to contact Bob at Flyin Miata for clarification.

Is life meant to be this hard, LOL.

Compression test car came up excellent and no boost leaks .

Currently tuned 7 psi.

What a mess.
Can you look at the injectors to determine size? Can you actually identify a MAP sensor?

I think the following link points to injectors being " Blue Tops".

As for MAP sensor still not ckear,

Makes you rethink that a comprehensive solution whilst having a high initial cost will give proven results without all the fuss as well as local support.

Ron, Was my PM not clear enough?

The injectors are in all likelihood the ones that come with the kit 410cc unless they were changed by your installer.

If they were I'm pretty sure you would have been charged for them and quite frankly bigger ones are not required at boost up to 12psi.
I'm running 11 psi and the injectors were actually struggling to supply enough fuel above 6300rpm.
A new Deatschwerks fuel pump solved that problem.

As far as the MAP is concerned, the original kit uses the OEM MAP and the tune by good tuners works around that.

Again it's extremely unlikely that your installer changed to a 3 bar MAP as it appears your install is straight out of the box.
A pic of the MAP sent to your tuner will clarify the issue and he will use the 'normal' tunes.
You will not be able to increase boost without retuning unless the 3bar is installed.
With the 3bar I can change pulleys on a whim.

As for local support, there isn't a great deal although Mania has installed a few kits afaik with great success and Bullet in QLD has done a Sydney car without a problem and which drives very nicely.
Again as I mentioned earlier, I'd be taking the car to someone who knows the NC intimately who can check your car thoroughly for problems.
More than one car that has run perfectly NA has not developed power after a supercharger install and it was found that the cam timing was out and apparently had been from the factory!

Thanks Rob,I passed your info onto Mike Mann. He is clarifying with Flyin Miata just to be sure.

I passed your info onto

I still don't know why no one has just looked.

That's what I said. Obvious
