What aftermarket ECUs work with/are commonly used with Porsches?

[mcgrews3]

2001 porsche 986 boxster S w/manual transmission -

Looking at Haltech tuners - was looking for a recommendation on which ECU would suit my needs?

* Primary purpose for my 986 is learning - DIY preferred and i look at working on the 986 as a hobby.
* Gauges and data that an aftermarket ECU can provide are very appealing
* I don't (yet) plan to track the car, it's a weekend fun car
* looking to maximize fuel efficiency and performance
* I live in CA so there are local restrictions that I should follow ;-)
* Have 74mm plenum upgrade and looking to add new air cleaner (987 or cold air induction) and a fabspeed exhaust

I considered the flash upgrades to the current porsche ECU - softronic etc. These seem safe but also "cookie cutter" and a "black box". Better than stock but I would like to be able to "look inside"/understand.

Recommend I stick with a flash tune? Or if going with a new ECU - what would you recommend? Anyone with motec/haltech/aem infinity experience?

Currently leaning towards a haltech so interested in Haltech recommendations.

Why?

You are not going to get much or any performance improvement and I think replacing the factory ECU is not worth it. IMHO

+1. You are going have to spend a ton of money on dyno time just to get back to where the car was with the factory DME, and won't see much of anything beyond that without doing major modifications to the engine internals.
