whats the differance bettween an 0fac and 0fab ecu on a frst, didnt no there were 2 different one1s thought they were all the same, and how much are thery worth??????

 

help some one

 

ones got a frequancy/pressure map sensor the other is a voltage/pressure map sensor

 

ofac uses frequency based map sensor
ofab uses voltage based map sensor

worth - well, i gave a tenner for an ofac one last time

theres a robbin coont on ebay at the moment attempting to get 150 for an ofac one tho he should stop dreaming

 

cheers lads

 

if you've got an ofac one for sale i'll give ya a tenner for it

 

ofac are worth pennies#ofab prob worth about £100-£150
i got £175 for my ofab ecu off ebay

 

yer i have got 1 iam gunner sell but i dont no wat one it is by looking,

they all look like shiny silver boxes 2 me, never really pay much atention to detail on them, its offf a jplate frst if thats any help.

 

whats the code on the sticker lable where the wiring loom pluigs in?

 

ill have to go 2 my garge 2morro and have a look m8 will let you no.

 

probably be a ofac ecu
think ofab were on the h plates

 

which is the better one out of the 2 though?

 

OFAB is better - more tuneable and you can use a 3 bar map sensor aswell

i'd like an ofac one tho purely for test purposes

 

test?

 

yup - doing some more research and development work and need an ofac ecu to test with - got an escos EEC-IV coming soon aswell for testing

 

OFAC is actually the best one... lol

They are easy to identify.. on teh label it will say either OFAB or OFAC... couldnt really be simpler

 

always thought that ofab was better for the use of the 3bar stu? ofac is easier to plumb in as it uses same sensors and loom as an XR2i iirc

 

Nope.. OFAC came about to fix all the problems with OFAB And the OFAC map sensor is 2.5bar to start with

 

ah, R+D, what you up to then, doing a new type of chip up?, my super chip may be playing up, do you know if they can be tested? (195chip)

 

arrrrrr - i stand corrected cheers stu


still want one for testing tho

 

i aint doin a chip no m8 - its engine testing trying differant flavours of ecu for turbocharged applications to find a good base ecu to work from

 

ah right, what car is it that your testing on?

 

i'm been a pikey and running a couple of engines on a makeshift engine stand in me garage - just finished playing with a rover V8

next one is dohc from a sierra, then an rs2000 and then going onto a 2.0i zetec

just basic tests like start, run, idle, throttle up and timing

if the tests are good, then i may go onto in-car testing

anyone with an ofac ecu they wanna sell me?

 

sounds cool mate., i got a ofac in my car and you aint having it lol.

 

arses lol

i'll find one floating round somewhere

 

im gunna have a look on fiesta turbo.com qiuck, will have a look to see if any on there whilst im there mate

 

theres a ecu and map sensor on fiesta turbo.co for £130 inc P+P, seem a bit expensive to me though

 

i'll have a look too - might give my mate mmommo a ring see if he has any floating round :P

 

its on page 2 or 3 of the parts for sale bit dude

 

theres one on there for 120 quid - map sensor and ecu - bit much for my liking, last ofac ecu, i only gave a tenner for

 

il'd buy that for a doller
