I'm not going to be running an SR20 (4AGTE), but I have spent alot of time on the net looking at ECU's and spoken to some people in the industry. This has led me to understand these basic things and I'll run through them-

1. Make a list of what you want you ecu to do for you. EG-Boost control, Anti Lag, turbo timer, data loggin, display ect.........
Once you have your list, match that to an ECU that can do all those things that you want.

2. Budget. Not just the buy price of the ECU, but fitment and tuning time. Remember that the more complicated the ECU the longer it CAN take to tune. That is a very general statement but one that applies. However in saying that, some of the top end ECU's have an auto tune feature that can help.

3. After sales support from your chosen company. Some are better than others

4. Make sure your ECU is upgradeable. No point spending all your coin to have a product that is out dated in 6mths time. If it's software is upgradeable (haltech for example) you will be able to keep upto date and make changes.

Some of the things to keep in mind.

Now what about some of the ECU's out there?
Power FC? I personally like them........that is when the engine is left where it came from. ie not a transplant. This is because they are not a true standalone ECU and will require all the factory harness and sensors and don't have any extra functions. They can run boost control (extra $$) and depending on the version have data loggin and a from of drag sytle antilag/launch control.

Microtech? A very good ECU for the price and well supported with lots of tuners in the market place. When applied and tuned correctly it will run virtually any engine smoothly. However they will run your engine and not much else. If you want to have a electronic boost control for your engine? Then you will have to buy it seperatly. Doing this alone bumps it up the pricing scale along side the Haltech E11.

Haltech? I personally think they are a better ECU than the Microtech. But you pay for it! But as I said above, you spend more upfront so come out even in the end. There are two things for my application that I am not keen about. That is, from what I've read, they don't always like factory sensors, which can mean you will need to fork out for new sensors. Not expensive by anymeans but more $$ you have to come up with. And the dash displays and way too expensive for my little datto. Plus I thing the boost contol "switch" is a joke.

For me this was my list of requirements-Data logging, boost contol, a form of dash display with engine specs, anti lag, upgradeable, be able to be removed and put to another car/engine, and enough outputs for me to be able to wipe my backside with, and the ability to run in closed loop and of an O2 sensor. This has led me to the Wolf V500.
I haven't made up my mind yet, but it does everything I need and more. Haltech is a close second, but doesn't have a dash, which will mean more $ for Autometer. And if I become an absolute tight ass, microtec and a "T" valve. However, the Wolf does have it's fair share of critics out there, so I am still not convinced of it's worth.

Above all, the most important thing, fine a tuner that has a proven track record with your type of engine and go talk to them. No point buying a particular type of ECU that you like and then taking it to him and expect him to be able to meet your expectations. He may not have the slightest clue how to tune with it. This could result in a poorly tuned engine, more dyno time due to the tuner learning as he goes.

Geez, I think that is my longest post on any forum. Better do some work...........
Oh another thing. Jump on line and down load their software and have a play with it to get a feel for what feature's they have.
This is purely my untrainned and un qualified opinion! Do the leg work and do some reaserch

power fc is the first pick for me and may manny others with the sr20det

hi guys im doing some research into a computer to run a sr20det and just want to know what you run.
cheers kurt
