The OEM JECS ECU is the most capable ECU you can use with your Version 1 -4 Impreza!
Consider the amount Subaru will have spent developing and testing it specifically for that model range and compare that to the likely budget of an aftermarket manufacturer.
Find another ECU with useful real world features such as closed loop knock control so comprehensive that it can retard ignition, add fuel and modify boost.
How many after market ECUS feature full active diagnostics and 3D boost mapping?
The only major disadvantage of the OEM JECS ECU was its inability to be reflashed. Thats where the ESL Live daughterboard comes in.
It allows the numbers in the OEM ECU to be changed to control fuelling, ignition, boost, sensor and actuator swaps (MAF, MAP, turbo, injector, etc). ESL Live will grow with any future modifications you have planned.
It is the complete solution for any engine specification.
The best part - At £295+VAT and mapping it is very much cheaper than any of the aftermarket replacement ECUs, and a national distributor network means local support for the product.
Don't be fooled into paying over the odds for a replacement ECU that is less capable than the one you already have in the car. This is a rare situation where you really can save money yet get more.
A national distribution network consisting of all the UK's top Subaru tuning experts is in place to ensure local support.
