Which aftermarket engine management system?
Discussion
Hi all, I am fitting a Rotrex supercharger and converting my engine to multipoint injection this winter and need a bit of advice on a new ECU.
I've fitted a megajolt aftermarket ignition ECU this year with great success, mappable ignition made the twin 40s much nicer, now I want to upgrade to full engine management.
I've used the Ford Edis ignition so I'd like the new ECU to work with that although I guess most will, the engine is 1970s Renault 5 Gordini based 4 cylinder 1690cc.
Up until now all of my tuning efforts on engines have been old fashioned carbs, cams and tweaked distributors, I'm not great with computers and I want the tuning process to be as simple as possible. I have an ignition map that works well from my megajolt that works well but as for the fuelling side of things I'm out of my depth.

Decide exactly what you need the ecu to do, both now and perhaps in the future. And then speak with your tuner to see what he can give you the best results with within your budget.
There are more than dozens of potential options, from cheap/basic, to anything but. But if the tuner is not capable with the system chosen, it'll all fall apart.

It probably comes down to the desicion on if you are going to do any of the install and mapping yourself?
If you're not, and if you haven't got particular expertise or a suitable amount of time to learn, then you money may be better spent on paying someone else to set up a system for you. In that case, i recomend finding a suitable local tuner and asking what there "pet" aftermarket system is. This is because you really don't want to pay someone to make a load of trial and error mistakes, such as are bound to happen when setting up and mapping any EMS system! A tuner who is familiar with a system will get through the tedious "first fire up" way quicker than one who isn't familiar, and they will much better understand how long it will take them to map that system. An dbeing local, you can easily revist them should any issues arrise or modifications be required.
The biggest single factor in getting a reliable install will be the quality of the wiring loom, and the security of the sensor fit. A properly constructed wiring loom, using suitably heat rated wire, correctly routed, and with high quality, well sealed interconnects is what is required. Yes, you can save money by lashing something together, but rarely is this actually a long term saving
