I've been skulking A LOT on this topic as economics are dragging out the process.

Adaptronic and yes, I would do it again. $1200 for all the components including MAP, injectors, TPS and throttle body.

I use LINK G2 and would stay with them. I changed from electromotive due to instability, poor performance, reliability problems. Buying a system is as complicated as buying a domestic car - you can get a base model, but you have dozens and dozens of choices in functionality depending on what you're going to do with it and they're all inter-related. For example, if I were to do it again, I would have used CDI ignition instead of wasted spark for performance and drivability. Does wasted spark work? Yep, but CDI is better for my application.

Megasquirt and yes. I may start with the newer MS-2 extra if I'd do it again though I really have nothing to complain about the system. It does what I needed. And I don't even find I need some of the niffty things like closed-loop, temp related adv/retard, ...
It is somewhat involved and very DIY though.

DTAFast P8Pro, yes and no. It has worked very well for me and the local dyno was familiar with it but I would go with megasquirt if I was doing another engine. I'll stay with the P8pro now that I've got it.

Megasquirt II. I'd do it again but it really is oriented towards DIY types of folks. I'm very pleased at the drivability (low speed responsiveness and warmup) and have been able to tune in just the air-fuel ratios and ignition advance curves I want at boost. In general it can cost less, but requires a bit more technical knowledge and willingness to experiment than some other options.

I'm leaning heavily towards the MSII, maybe even the Sequencer, so you MS guys I'd love to hear more from. I'm a total DIY'er. I've set off the CO alarms in the house twice today trying to dial in my WUR with a wideband... I miss tweaking fuel trims on my Audi S4 with a laptop.
My budget for my EFI project got zero'd out, and I'm actually enjoying the prospect of EFI'ing my car withOUT swapping in GT2 cams, twin-plug heads, and a GT35R, literally JUST converting the fueling and ignition. Based on the vacuum gauge tests I've done, I'll access potential gains just by clearing the intake path to the inducer (there's 5"hg at 6,500rpm at the inducer). Not to mention dialing in fueling and ignition advance.

I have a fully built Megasquirt II with twin edis ignition units and their wiring harnesses, twin EDIS coil packs, just needs a trigger wheel on your crank and a sensor and its ready to go. STIM and all the extra bits and case, cooling fan. I had a great time building it up but wanted something with a full-service team behind it. My kits for sale if someone wants it. Otherwise I'll play with it on the 2.7.

Its s good setup with an active community.

Electromotive Tec3r. No I wouldn't buy it again. Piss poor company with a Piss Poor attitude towards their customers.

Sounds like the MS solution is not a bad idea for those of us with some DIY'ness.
I spent my weekend FIGHTING with my WUR... I hate this frigg'n fossil running my engine. Screw my budget I'm going to start Craigslist-ing off some other toys to get this project off the ground.

I have a DTA P8 Pro. Works fine and I'd do it again. I had it tuned initially by someone with lots of experience (while I watched), and I've made a some changes since then on my own. For the main maps at least, I find it to be pretty logical and straighforward. With a few exceptions, I don't think it matters that much which ECU you're running; it matters how it is set up and tuned, and by whom. I would still not attempt to tune an EFI 930 from scratch without the right equipment and help from someone who is very knowledgeable about the specific system you choose.

Motec and I'd use it again, but of course it's hard to justify financially. My optioned M600 ECU is the most expensive component on my car .

My recommendation: Find your tuner first (and yes you need a tuner) and buy a system they're comfortable with.

Listen to the above knowledge. Many people will tell you they can tune whatever you have but it is simply not the case. I used Autronic, one of the most powerful systems for the price. Not many people tune it and it is no longer for sale so there is pretty much no support. If i did it again I would go with a system that is more capable than the motor or tuner to leave room to grow in the future. DTA fast, Pectel, McLaren electronics, Bosch MS, Motec, EFI Technology, those would be my first choices not necessarily in that order. I would look for a system that can handle 6 injectors and 12 sparkplugs, operate in closed loop, capable of data logging, had multiple programmable outputs and has a CAN Bus link. Yea it sounds like racecar stuff but its the same stuff in a street car only this is programmable to your liking.

Ok is there a system ( say a Bosch) that's being used in a production auto that is available and someone's doing aftermarket software that can be tuned?
