Default EFI problem

I have no problem starting up a cold engine and everything is fine. But when the engine warms up sth happens - when pushing gas engine dies and seems like no power is transferred. What may be the problem: CPS? idle engine? Coolant Temperature Sensor? 3-bar MapSensor?

haaaa, u say u have a 3 bar map sensor!! has the ecu been mapped to run this?
so when u say 3 bar map sensor, u have a OFAB setup! has the ecu been mapped to run a 3 bar? cos standard should run a 2bar ithink, or maybe its a 2.5, but deffo not 3 bar...

i had problem with mine when i first converted, it would start, but wouldnt rev properly! it was the ECU that was faulty..

has it got a Map Supressor in the loom?

no supressor

not been mapped for the 3 bar

people say that you can run it without the supressor but if u ask me its not there for no reason,

it could be either of those 2 mate,
dont think it will be you ISCV..

ithink you may be better talking to safechav about this mate..

has it been setup since u converted? as when i first converted to EFI it ran mega rich the co2 level where at 10.5% and really they need to be around the 2.5 areaish

It's worth noting, that these supressors are no longer available from Ford, and when they were available, they were Ł100 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 Ł50, delivered.

The suppressor shouldn't be an issue, that was a revision to later cars, certainly wouldn't go a miss though.

But, i agree...........3 bar MAP and no chip
