Why no 'Chip/ECU' tuning for MX5's ?

I'm puzzled. Why are there no shortages of magazine and Web adverts for Chip/ECU tuning for various sporting models from BMW, Ford, Audi, VW and Mazda etc...........except MX5s? Everytime a new model from the above manufacturers comes out it seems to be followed by several tuning companies offering performance packages usually starting with Chip/ECU upgrades and often at extremely reasonable prices. I know there are induction and exhaust improvements available but the missing link is ECU tuning. Is the MX5 ECU that hard to crack or is it simply that tuning companies have looked at it and decided they can't make any performance improvements to it?

Any thoughts, comments or explanations?

Cheers

Steve

    Steve, a company out here in Australia offers aftermarket ECUs for MX5s. Maybe the brands it sells are available in Britain. Check its website at http://www.mx5mania.com.au and look at the ECUs. They do export orders but surely you will find somewhere in your country. I don't know whether you can retune the original CPU or does it contravine existing emission laws.

    I understand it's because these upgrades are usually aimed at forced induction engines, especially turbo diesels. These engines often have huge untapped potential limited only by the ECU. For example the BMW 318d & 320d engines are to all intents and purposes identical (same capacity despite the badging). The lesser engine is effectively strangled by it's tuning. The manufacturers can hence charge more for what is essentially the same thing. As standard MX5s are normally aspirated they don't have the same potential for tweaking.

    Incidentally this forum was enlivened by Tark Malbot's heroic attempts to supercharge his MX5. Any update from the new owner?

    Good point that Steve, I'm also interested to know why this is.Curious

    Some of it appears to be down to the fact that the MX5 is seen to be a flat hat and string backed gloves car for the retired if you read Banzai, J-Tuner or any of the other modded car magazinesEmbarassed It is not taken as a 'street' or 'fast' car for the younger person who might blow his months wages on tuning mods.

    Chipping isn't what it used to be anyway as theres no 'chips' as such involved. You plug your lap top into the OBD11 port and change the settings in the ECU or even add a small bit of software to do the job - Note the best ones can't be detected by the main dealers service kit so no warranty problems. There are companies out there doing this for the MK3 and most seem to be claiming 10-15% on a normally aspirated motor. It works best on diesels or turbo/supercharged motors but the software and cable is out there to do the MX5 - you can even buy it on EBay!!! This is probably best done after you've done all your other mods like exhaust, airbox, etc to get the most out of the lot.

    The only place in the UK that I've seen advertising the fact that they can do it, the main problem with the MX-5 is its complex code used in the ecu's software (a hybrid of ford standard code and non-standard code thrown in by Mazda) and the amount of regional variation/changes/updates between batches of cars manufactured at different times (Sniper says theres hundreds). 

    Sniper leads the way in the US, but even they have never fully got to grips with it, particularly with providing flashes for 5's outside of the US, hence the global cosworth tuning fiasco. Cosworth have all but given up on it, leaving the tuning now to the consumer and no longer offering tuning support with the cosworth outside of the US.

    That'll explain why theres less than you'd expect but T.D Performance are quoting the MX5 2.0 specifically as +16bhp. DCP Tuning are another that reckon they can do it. Others (ISTR) Monster near Nottingham claim they can do it..though they specialise in other vehicles normally. Obviously it's not the normal run of the mill job from what WaNoS says but the willingness to take it on is driven by requests and cash. I'd guess that a large percentage of MX5's never go much further than a K&N and a back box?

    I'm about to do a bit of a back-pedal here. MX5 MK3's are now being raced as of this season so ECU work will get done rapidly I suspect. Best thing is to go to the tuners the teams are using. Secondly all the chip flashing gear that is easily available seems to cover everything but Mazdas...the kit is out there but not cheap according to my mate who is running Megajolt and Megasquirt on his kit car.
