sorrentoaddict 1 Posted December 28, 2006 Hi guys, any opinions as on which brand/type would be the best-buy choice (apart from MS-II) ? What is needed is the simplest & most cost-effective aftermarket ECU that can manage injection and ignition on a simple, atmo MI-16 race engine (on home-made TBs). I would appreciate your own experiences and general information. Are there any hidden "catches" to be aware of when shopping for such low-cost ECU units ? Many thanks for any input.

petert 586 Posted December 28, 2006 (edited) I'm undeniabley a Haltech fan. It's very hard to beat the E6X for value for money on a 4 cylinder. But it all comes down to the support around you. Having said that, I run an Autronic on my race car! On an XU pug, the critical thing for my mind is being able to run wasted spark ignition (2 ign. outputs) from the OEM crank sensor. Running aftermarket input sensors is very boring when there's already one there! If you want to run direct fire (4 ign. outputs) and/or sequential inj. (4 fuel outputs), then you'll need a reference sensor as well. I use the std. XU10J4 cam sensor for this. Additionally, low cost units struggle to manage large injectors at small idle pulses. This is an issue for Mi16's as you'll need to fit larger injectors, thus your idle pulse will go down. Edited December 28, 2006 by petert Share this post Link to post Share on other sites

I know a couple of people running megasquirt ECUs with 440cc injectors on their 325i turbos and they don't seem to have any low resolution problems Share this post Link to post Share on other sites
