Has anyone here used an Emerald ECU from the UK in upgrading to EFI and had any problems, including when using a rolling road to tune the car?
Depends on what market. Definitely in the Patrol world and the street scene in general. In the motorsport world however, it's either Motec or Emtron. I've recently purchased a KV8 Emtron and it's an amazing bit of gear. The fuel modelling is way ahead of anything in the Elite range. It looks expensive at first glance, but when you consider it has built-in lambda controllers, it's excellent value.Haltech seem to be the most popular now.
Tried these guys in melb?Have gone with Haltech 750 Elite series with universal wiring loom. Plus bought their MAP sensor, O2 sensor and air temp sensor. Already had Ford Fiesta crank sensor, coolant temp and knock sensor but having trouble finding female plug connectors. Rare Spares and Ford Spare here in Canberra unable to assist. Any suggestions?
Hi Alex thanks for the tip. Ordered connectors for air temp and crank sensor. Will see how they go when they arrive. Unable to find connector for knock sensor. Option are to do without or get one from Haltech if supported by ECU.Tried these guys in melb?

You need to blend it. For modified engines and multiple throttles, I setup the fuel on TPS and ignition on MAP.I have found that on modified naturally aspirated motors that I don’t use the MAP sensor and set up the injection using throttle position and revs.
On a multiple throttle engine, combining/adding the vacuum pulses into one line, helps overcome the irregularities, giving a more stable signal for the ECU.The reason being with a biggish cam the vacuum is low and bit erratic at idle and low revs, making it confusing for the ECU concerning what load condition the motor is under, even though it would still be looking at throttle position in conjunction with the MAP.
Roll on the 4CV Alan!I have not used or know anyone in Australia that has used an Emerald ecu. Given Australia seems to have more programmable ecu brands than anywhere else, I would go with a Motec or Haltech.
These are well supported, well known and the unit required for your use is not overly expensive. I admit to having 3 old M4 Motecs, 1 of which is in use, that I did the wiring and basic programming myself, and will be fitting one more to the 4CV. They are about $500 ea, but are old comparatively.
A new Haltech Elite 750 is $1600 and I would expect would have all the functionality you would be looking for, if you are looking to inject an 807.
Goodness, only 6.5 times the power to weight ratio.Haltech seem to be the most popular now. Andy Wyatt, the guy behind Adaptronic is now working for them and I believe has sold his business to them. The old Motecs I play with are very easy to set up and tune, given I was able to wire and program it to be drivable with a similar quad throttle body set up you are looking to use in an old car not made for injection.
Eventually I will be injecting the 807 in the 4CV, but I have tamed down the cam thinking I don't need a 150Hp in an unstable 650Kg car. Might only be 130 now.
