why do u need a supressor on a ofab efi conversion

 

you dont i never had one on mine lol

 

Ive been told you do on the ofab loom,been looking for 1 4 ages

 

no you dont mate

 

surely ford wouldnt of fitted it if you dont need it????

 

i mean its not a nessesity, do you know what they do?

 

There must be something in all these topics https://passionford.com/forum/search.php?searchid=71273

 

go on what do they do. been building mine with the doc he says you dont need them and his mk 3 van never had one fitted

 

Yeh wot do they do then if u dont need them?

 

its just to stop noise ie electric noise as long as your earths are good you wont have any problems honestly

 

i was told these reduce the current which is sent to the ecu,and without these fitted it gives the wrong info to the ecu and can damage the ecu........

 

no mate thats incorrect lol who told you that??

easy way to explain it . . . on some cars when you get that alternator 'noise' through the speakers or fuel pump and so on if you put a suppressor on it stops or at least reduces the 'noise'

 

Somebody has been confusing suppressor with resistor when they told you that...

 

ive seen those resistors on ebay daz you put them in your air flow meter wiring and you gain 20bhp

 

im sure ive read it somewhere....will look for it....

 

Thought i was right and that id seen the info somewhere before......www.rsbible.co.uk

"You should have a suppressor with your OFAB MAP sensor.
If you do not have this connected, you run the risk of damaging either/or the MAP sensor or ECU. It will also feed the ECU incorrect information, causing running problems, and/or damage to the engine. It may seem however that the engine is running with no problems.
It's worth noting, that these supressors are no longer available from Ford, and when they were available, they were £100 odd!
However, if you need one, speak to Kenny at http://www.motorsport-developments.co.uk/ He will be able to supply you one new for £50, delivered."

 

if your map readings are out it cannot damage the engine due to the map! i dont see how it can damage the ecu at all and why would this just be on ofab and not ofac just bacause it has a different map sensor on it . . . .
