right i got it so i just need to adjust the req fuel by small amounts e.g

from 4.6 to 4.2

then adjust the ve table if it requires it

hay there mikael i dont suppose there is any chance you could send me your mapp again i just cant get the car started again i put everything back to the way it was on the mapp but still nothing

many thanks rich

Here you have, i put together a couple of starting mapps, the ignition table is kind och low on all but it´s for safety reason so you need to adjust it somewhat when you got it running good

You always need to adjust the VE table but you need to adjust the req fuel so close you can

thanks for that mikael got it running again now ill be more carefull what i change on it:)

hay up mikael how it going,well i think im getting the hang of this mapping buisness lol
i also relized that i was still running my standerd injectors they are only 160 cc or so so ive just changed them over and ill see what diffrence i get

thanks rich.

no nothing i cant get it started at all now i was wondering u sent me a safe start up mapp which 1 is it

thx rich

Did you use the startmapp_TFI_6cyl.msq that i linked to i bit up in this thread? it should work directly with 350cc injectors with 3bar fuelpressuare

yes thats the 1 i used i go to start it and it starts then cuts off and fluds the engine

i was just thinking are you using a standerd fuel reg

Yes, standard fuelregulator is more than enough

do u think i should try putting the req fuel down to like 200 cc injectors

I think you should try some different values until it runs

values in the ve table or the req fuel

The req fuel of course!

Í can´t explain this no more, this is basic if you dont understand how this system works then read the read the manual at least 10 times, if you still don´t understand, read it 10 times more. And if you still don´t understand, pay somebody to tune the engine for you

no probs lol:) i think i got it now ive just turned the idle values down and i seem to be making some progress

hay up mikael going well now all is ok aprt from i cant seem to get my idle down but i will figure that out turned all my fueling down a bit now ticking over well now just shes sitting at around 13000 revs

Remove the iac contact and se if it gets lower

yea it does a lot lower

hi mikael just wondering are you using a pwm valve or a on/off switch i still cant seem to get my idle down,the only time i can get it down is when i unplug my idle valve then it goes down to 600 rpm

I dont´s use idle valve. I adjust the idle mechanically

ah thats were im going wrong great ok that makes sense thx mikael for your help hopefully i should be ok now

Doesnt fords have EFI systems? my 2.9 does:/

yes they do but i put a stand alone management in

hi mickael sorry ive not been been madness at work i was wondering what injectors are you running and what are they off

many thanks rich
