fitted a cosworth engine into a mk2 escort

i have fitted a 4wd engine using a 2wd sump
rainbird plenum
megasonic dump valve
3bar map sensor
rs500 intercooler

standard ecu

problem i have is

i get everything wired up and tryed to start it today
after playing with the ht leads and getting to run its seems to be ticking over very fast 3000revs

am i missing something do i need a animal valve????

the guy doing the wiring thinks the ecu could be at felt???

please help after 10months of building the car and finding a brand new cosworth engine from tickford ford

i cant believe im still having problems

 

Ive had this with my last one and it was an idle control valve hope this helps as im having a headache with my latest one cheers.

 

is that the red thing on the throttle body????

 

no mate wot he means is the uver thing on the throttle bodie that sticks out and has a plug on it

 

or you need to ajust the throttle bodie it self as there are 2 settings on it 1 is the air and the uver dose the butter fly inside the throttle bodie

 

disconnect the idle speed valve and see if the revs drop its the stubby tubular thing on the throttle body just disconnect the plug while its running

 

the red thing is the ( throttle position sensor ) and you will have set that up as well mate you have to use a volt meter to set it up

 

i pulled the plug off the idle valve when it was running to nothing changed

we tried playing with tps and nothing the tec guy thinks its no good then again

he has told me the ecu is no good aswell ?????

 

free sunday dinner to anyone who can sort it for me lol

and as much tea/coffee you can drink

 

ecu is possible but unlikely have a spray around the inlet manifold with brake cleaner or something similar and see if the revs pick up if they do it could be an air leak only need a small leak to raise revs a lot while not under load

 

i can not see it being the ECU mate it getting to much air take the pipe off the throttel body and have a look and see if the butter flyis closed if it is then start the motor and see wot the revs are doing if its still to hi put your hand over the throttel and slow the air down and see wot happons if its still running you have a very big air leak

 

have you got a up to date photo of the motor ther might be some thing you have mist

 

botters


you may be onto something when playing the the dizzy to get the car to run im sure i could feel air from the lower part of the plenum

if this is from a bad seal could this make the car rev so high?????

im getting a ecu tomorrow with a 300 bhp chip

if you think it could be the plenum i will have to strip it back down and try and reseal

i used a new gasket and sealant when i did it the first time but im sure i could feel air

 

 

check youve got an idle screw in the tb,as above spray wd 40 around the inlet plenum when running and if the revs dip then youve found a air leak,it wont be tps i doubt but you can also unplug this and still run at idle...
What chip you running ecu etc???

cheers danny

 

just see pics above(lovely looking motor mate)and see you have idle screw in
Why is the tb upside down???is it std tb??im always sceptical about those blow of valves as iv seen these cause tick over probs but doubt it,do the leak test mate could even of ripped the inlet gasket plenum to head???

cheers danny

 

buying a ecu from IAN RS2K its a L1 with a Ahmed 300bhp chip

 

make sure your on a pf01 tps then mate or youl start chasin g your arse..


cheers danny

 

this is not about the problem your having with the motor running but one thing i have sore is the size of the pipe you are running on the pumps are they big anuth to do the job wot size is the i/d of the fittings coming of the tank

 

thanks mate

im getting the ecu tomorrow night and i have a spare brand new inlet gasket
so sunday ill strip it down again lol and try new inlet seal and try and find a way to get a better seal on the plenum

the engine was brand new for tickford ford and had been bench tested before me getting it so i know the engine is good buy ive had the inlet of and fitted the rainbird plenum since

god i hope this sorts it
taken me 10months so far to build the car from a rusty shell and had it booked in for a mot next week :-(

 

fuel lines are braided ptfe teflon dash -6 all the way though

 

all very good but wot setup is the chip for and wot have you got on your car......injectors

 

Standart ECU and 3bar Map?? I´t doesn´t work.

 

dont worry mate it wont be anything serious,if you ever need any advice just pm me..
as coley just said though check your fuel line sizes..

cheers danny

 

the tps is the standard one from a 4wd 1995 green top engine

is there a code somewhere on there to say if its a pf01

 

i tryed it with the standard map sensor no difference

thats why im getting the other ecu tomorrow night

 

could well be the problem mate give all the sealing surfaces a good clean with light sandpaper and fit new gaskets, i wouldnt use silicone sealer as some gaskets dont like it i would use hylomar blue if you can get some its the dogs danglies for sealing anything

 

depends what map its got if its 3 bar itl be fine but just noticed hes running std blues so why be on 3 bar???
Needs to have the right map etc to run right!!


cheers danny

 

blue ones ????

 

And with the L1 ECU you need a 2wd TPS.

 

4x4 TPS are black 2wd are RED and when you go from RED to BLACK you have to swop the 2 out side wires

 

that will be a pf09 then mate and will be wrong for a l1 ecu ,you can switch the outside wires around that goes to the tps plug but realy you want to run a l8 ecu and make sure the tps wires are configured...it will say on the outside of the tps case what one it is..

cheers danny

 

should i try resealing everything
replace the 3bar with the standard one untill i know what the new ecu should have??? ie what colour inj?

 

not always,all the ones you buy now are black but oe factory were red...


cheers danny

 

firstly what engine loom you running??ie 2wd or 4x4 etc then go std injectors std map sensor pf 09 or 01 and suitable chip and ecu then atleast theres no mismatch...
As said just ask if you get stuck mate..


cheers danny

 

yes mate does still sound like an air leak to me let me know how you get on

 

yes it has pf09 on it and i know the tec changed the outer wire's around

 

At the end of the day the car will run on just about any set up but very ruth wot you have is to much air getting in .its the throttel body setup / air leak im 100% shower

 

its a 4wd engine but 2wd loom
tps has pf09 on it
