PNP S4 comparing to my Brothers PNP MR2
 

My brother was thinking about buying ATS Racing for his MR2 after I mentioned that I was getting the Adaptronic S4 PNP to run with the new BNR S5 Stage turbo that I will be purchasing. Already gave my CC # to BNR lol. (New design that replaces the whole CHRA!) No more T04B 60-1 turbo for me.

How do you think the two ECU's would compare as far as price and features?

At a quick glance it looks nice that you just plug in your boost controller. Still not sure how the ADAPTRONIC will control boost on the S4. Also neat that it has a built in wide band. Not sure how accurate that one would be.

The ATS kit uses the ECU Masters ECU. Its a new system from a British company. You can get the software and manuals from their site. Spec sheet is very solid and the software is very nice. If it performs as well as its spec sheet, it'll be a good kit. If you all go that route, I'd love to hear reviews.

Check that. Appears they dissolved in the UK in 2012 and are now based out of Poland. Odd... Did find a couple recent references to people using them while Googling. But not much feedback.

I couldn't find much either. Reason why I posted here was to see if anyone else has heard aout them. I told my brother to be careful running a computer he has no info on but he said ATS is running alot of cars with it. I know nothing about MR2's.

My suggestion to him was to get a PNP unit. This way you stay emissions compliant.

Just stay away from Hydra! I know those were big with the MR2 crowd for a while. They're abysmal. You might try asking over at EFI101. A lot of European guys on their that may have some insights.
