Aftermarket computer options

Just looking around at aftermarket engine management options for my engine. Those of you with aftermarket systems, what are people running, what was the cost and are they happy with them. I have been looking at the EMS 8860 & 4424 but at the moment they cannot control the ford IAC so have no idle control which will be a problem for me.

Not having the IAC is not critcal if your car is a manual and you do not use A/C.

Re: Aftermarket computer options

Firstly its a auto and secondly it has a fairly lumpy cam which even with IAC has problems with idle sometimes. Most installers have said it is not a major deal and they should be able to get it to idle fairly well but I just would prefer to have the ability to fully control idle, if needed, especially if I am forking out that kind of money.

Re: Aftermarket computer options

have you looked into what the twEECer cant do with the ford eec compared to what other aftermarket options can do? one way to look at it your ed should have support with the twEECer, and it obviously runs, so now you have a baseline to finetune and extract that extra pwr and better drivabilty, while still being able to control your auto trans shift points ect..... for a fraction of the cost of a full aftermarket system with all the abillities of one. worth a thought.

Re: Aftermarket computer options

Yeah still considering a Tweecer but with the need to purchase a supported EEC (mine is not), the tweecer itself, a MAF (most aftermarket systems dont need one) and then tuning, the tweecer works out similar cost compared with aftermarket systems. BTW, the tweecer cannot control australian auto shift points. Reading a lot of the tweecer forums, many people have a lot of problems getting the tuning correct with the tweecer even with data logging RT version (again not compatible with australian EECs), and some of the tuners I have shown the tweecer system to have also raised concerns with a few things. Still, I have not rulled it out, just want to look at all the options before handing over the $$$$

Yeah update for the 8860 should be available in the next 4 weeks but I don't want to wait that long if possible, and if I buy it now, it has to be sent back to the manufacturer for updating once released. $2k is pretty good, dis that include tuning. Most places are $2300-$2400 installed and tuned and about $1700 for the lower spec stinger which should also be suitable for my needs. The Tweecer is $900 or $1100 for the data logging version. Installation only takes a few minuted but I then need a supported EEC, MAF and tuning so all up I am figuring on $1500-$1700 plus tuning.

Reading through the specs of the 8860 and 4424, it looks like it can actually control the IAC because ford uses PWM IAC's, not stepper motors. Have to go back and talk with the EMS guys again I think.

Re: Aftermarket computer options

Yeah, i can controll the idle with the ems easly.
The PWM and base duty does the trick.

Thanks for that. The EMS distributors here in SA said that they cannot, I guess they assumed the fords used a steper motor setup.
