Microtech problems?

I understand, but let's face it... a Pectel SQ6 would run you several 1thousands of dollars.
Picking one up second hand is really looking for a needle in a haystack.
Cosworth may be in the UK and relatively easy to get to but on the other hand, they have never tuned a Rotary to my knowledge so how sensible would that be.

Cosworth are probably a buncha n00bs who can't do much.. boy I am sure glad you spoke up.

LIke I said, I've been a Cosworth fan since my childhood and deep down I still am, but then I'm thinking of the Ford Sierra and Escort Cosworth, 4 cilinder rally cars etc.
Mostly cars that never or rarely made it to the US. So in th end I don't doubt Cosworth UK will have people who know their stuff, but the Rotary aspect is still another deal.
That being said, I've been digging around some more and have come up with other possibilities
- Tec3r: seems to be used rather often but lacks in and output channels and no possibility to keep the OMP so that's a NO for me.
- Link ECU: Commonly used in Aussie and pretty succesfull on race/drag cars. No idea about pricing though
- Autronic: fairly new name to me, but seems to be used on the higher end builds. Seems to have decent hardware and their website seems to have free downloadable software.

Is The P2000 a general ECU or are there various editions of it?
Does it work with OEM sensors on the 20B (given recalibration probably) or is it necessary to use Halltech material?
What MAP sensor are you using. Halltech or GM 3bar sensor (others?)
What other Haltech ECU are capable of running the 20B? P1000? 5 Sprint?...

There is only one P2000 and its a universal ECU. I installed a GM coolant sensor and used my old fast reacting FD intake temperature sensor. Its customizable, you can use whatever sensor you want as long as you know the calibration, it comes with some calibration files already. You can download the software to find out which are already pre-programmed.
I'm using the GM 3 bar map sensor but it has a 22 psi internal map sensor if you want to use it. I don't like running long vacuum lines for a map sensor into the car so I used an external one.
Only the P2000 will run a 20b. They're old E11 will run it but I wouldn't suggest that, why buy an ancient ECU.

You guys just don't get it, they aren't even on the same playing field..
It's like comparing oval-dirt-track cars with Indy or Champ ..or hell the GroupC cars.
The ECU's mentioned in this thread dont even compare - hell not even the software is comapres to CalTool. Guys, I'm not blowing steam for the sake of blowing steam. I've had a few Pi ecu's open on my workbench for surgery, including an SQ6. The hardware design alone trumps these common ecu boxes. I dont even want to start talking about the micro-controllers, etc.
I'll stop voicing my opinion on the subject :-)

Exactly, Although I have no problem with regards to technical design that some are old school and others on the high end.
But prices vary and rebuilding a car requires money. I'm not saying everything needs to be on a budget. Some things need to be done right from the beginning, but then again every budget has is limit in the end.
Pectel is still in the running so to speak, and I guess Haltech or Motec aren't that bad either.
Considering racing history they also have something to account for.
All in all, it's worrth considering and looking for the best buy that thicks as many boxes as possible.

my .02:
Microtech is fine, as long as you don't need configurability. They are cheap, simple to set up, and easy to tune. They aren't very powerful, but they are targeted at people who want to get the engine running and tune it on a budget without a bunch of bells and whistles, and they are fine for that.
Haltech is similar to Microtech except that the inputs can be reconfigured. Unless they have updated it since I used one, Haltech has TERRIBLE software, which rules it out for me.
Megasquirt is not worth the trouble unless it is an application that is very well supported, and a 20B isn't one of those. The big issue for me is that as with any complex DIY item, when there is a problem it is much harder to diagnose because you can't make assumptions about what is or isn't set up or constructed properly.
AEM is basically a knock-off Motec, and as such is a really nice ECU. They don't make one specifically for the 20B, but they are very easy to set up and have super powerful and user friendly software. This is my choice of ECUs for everything, because it has enough hardware capability to do nearly anything and the software to back it up. That said, you need to know what you're doing to get all the features set up, and it isn't super well documented.
I use Motec stuff at work, and if you can afford it, it is awesome, but sadly, most of us just can't justify the cost. I have not used Pectel or Pi, but I assume they are similar.
Anyway, as to the original question, the Microtech is fine, and has no major issues, but with more capable ECUs getting cheaper and coming onto the used market, I think they are for sale just because people are moving up to more complex systems that can do things the Microtech can't. If you want something simple and cheap, by all means by a used LT12x. You will get the car running and probably be happy with it, and you can always sell it and if you decide you need something it can't do.

not sure which one you're talking about but the platinum stuff is actually really nice, and it makes the older stuff scrap

Don't shoot me but I stumbeled on the Youtube vids from Aaron Cake and his RX5 rebuild.
He is using a Megasquirt MS3Pro which has an upgrade processor and print board.
Loads of in and output, some specifically for rotaries...
