Have just had Tighe cams installed and cam gears installed on my 99 mx5. Has full lock stewart exhaust system and cold air intake, lightened flywheel and heavy duty clutch.

Idles around 1500, a bit lumpy, but noticeable jump in perfomance mid range and top end.

In order to get the most out of these cams (805), what aftermarket engeine management system would be best. Budget stretches to around $2000.

Lastly, any recommendations for installing, tuning same in BRISBANE.

i would reccomend the guys at chiptorque. they did a great job on my car and the total bill for ecu, sensor and tune was 2100. if you tell them you have a 2k budget they will make it work. but that said i am sure there are many other places around that will be able to do it for you.

Novice, there's a mob on the northside (eithe Kallangur or Clontarf or maybe even further north).
I can't for the life of me remember the name. It's something like Redline something something. Maybe someone on this forum will know.
The shop specialises in Wolf EMS and he has done several BP engines in 323s/Familias.

If the GC is easily accessible for you, then go for Chiptorque.

Otherwise, pick an aftermarket ems that you fancy, ring the head-office and ask wheren an authorised installer/tuner is.

There is also the DIY Jaycar DFA (Digital Fuel Adjuster) that several ppl on the forum rave about. Ask Fatty and green_comet.

I wouldn't go a \"chip\".

Look at a proper ECU that will be able to be retuned as you do more mods.

Jaycar - stores all over Melbourne.

You should read up on the Megasquirt plug and play. It will be around $900 landed, install is a breeze. You can even remove the MX5's restrictive MAF, and use the Megasquirts onboard MAP sensor. Then with the left over money, you can get a really good tune done.

Thats what I would do..

Thats what I am going to do..if I can't sell my car and I end up putting hot cams etc in it instead

Hmm there could be problems with the NB motor I believe with running some computers that people are recommending here. Supposed they have a wierd CAS signal out of them that isn't easy to work with.

Haltech is the best bang for buck on the market currently, but again I'm not certain they can run the later model engines. I'd email them to find out, most people I've heard who have dealt with as far as questions and answers go have been happy with the advice given though I have no first hand experience with dealing with them.

Actually I forgot it was an NB, the Megasquirt plug and plays are only for NA6's, and NA8's soo far.

Thanks J! I think I'm being referred to here. The Motec standalone was AWESOME when I was up it (embarrased a few cars I had no right to) but terrible the rest of the time....

I've got mine booked in at Allstar Tuning for a haltech miniceptor tomorrow. It's quite a sofistimacated interceptor (paradox?). This is to compliment the new Tighe Cams 805c (or similar) cams that went in over the weekend. I'll let you know how it turns out.

Ron, do you have a noticeable increase in lifter noise with the new cams. Mine sounds a bit like a twin-cam tractor at the moment. Hoping it settles down after a few Ks....

cheers,
T

Can't say I have noticed any increase in engine noises. Major thing is watching it fluctuate at idle from 1000-1500 revs. The car tends to shake from side to side.

It doesn't like starting on first turn of the key and it doesn't like taking off straight away after starting. I, was told the A/C might not work as efficiently, but having just tried it, no problems noticed.

I, will speak to John Kraschnefski and John Whittaker re their recommendations.
cheers,
Ron

Thanks guys, I did read all your replies.

Chip torque is a definite possibility, heard good things about them.

Will also talk to John Kraschnefski and John Whittaker re their suggestions.

Keep you informed.

yes as mentioned i really like the jaycar dfa but i only have experience with it on an na6. it is just a fuel piggyback tho, it doesn't do timing or anything else.

not sure how the megasquirt works on a 99 nb either, i know there are issues with the nb engines that have the variable valve timing or whatever its called.... i don't know if your car is one of those.

in general i don't know much about nb's , sorry.

Shouldn't be any VVT on a 99, just a variable intake plenum.

I won't make a comment about the MegaSquirt, last time I called it a \"porn name\" and Steve went all emo on me.

Ron, do yourself a favour and don't talk to BT&T
