Obviously every management system has advantages and disadvantages. Likewise there are many opinions regarding it. Here is my take on it
OFAB or OFAC is very expensive to map and can only be done by a few people which ensures this keeps the price high, as I wish to develop my engine specification in the future having more than one map done for my car makes it not cost effective, for this reason
Go-tech... I simply want a choice regarding who maps my car, I do not wish to be forced to use a specific tuner or mapper.
Megasquirt simply because its a educational project lacked the support, parts and features I desire, im not knocking the system however I did not personally feel comfortable with it.
Omex I never really looked at for some reason.
The reason that I went for Cossie is that I believed if it was enough for a 400-500bhp cossie it most certainly would be capable of delivering the required performance for my Escort.. The cossie management is well known, reliable, its proven in motorsport and is capable of being mapped by a vast number of tuners around the UK.
This can be an important consideration for many people especially if your preferred tuner does not promote a specific management.
The resale value and desirability of cossie management ensures that much of the original costs can be recovered when selling second hand.
My ECU which has been modified to take Dizzyless ignition, Air injectors and water injection along with a pectel monitor would sell for near on what I paid for it tomorrow without problem, in fact I have been asked to sell it... the devaluation is minimal when compared to some of the other managements I investigated.
Many people point out the age of the cossie system as if this reason alone for not considering it, however by the same assumption we should scrap all the escorts and cossies as they are now around the same age also.
I personally never had an issue obtaining all the parts I required and am convinced that I have made the correct choice for myself
Everyone has different things to consider which effects their choice and I think its important for people to investigate all options available.
