megasquirt

thanks mikael im not sure is the injectors i have are too big they are 480cc and not sure if the ms 1 can take the resaloution for them so i might have to get some smaller 1's

No it´s no problem, but you need to adjust the map when you are using bigger injectors than the map is made for

ah i c ok no probs car is all running ok now got it mot'ed the other day and its running well pulled well i just need to tweak the mapp as im still running the start mapp

hi mikeal just wonderd do you have a mapp for the m/s 2 i am upgrading to ms 2 soon or will the mapp for the ms 1 work on the ms2

thx rich

Why uppgrade? MS1 works fine. I don´t have a mapp för MS2, you have to construct your own now

you can controll the fueling a lot better were the ms 1 you can only go from 0.3.down to 0.2 were the ms2 you can go from 0.3 down to 0.299 i find its a lot more precise plus i cant get the car from overfueiling when i put the bigger injectors in

If you cant get the car to run good with MS1 than you cant get i to run much better with MS2.

I have tuned a car with 850cc injectors on a Cosworth 4cyl without to much problem.

630cc injectors on a Ford V6 is no problem, how big is yours?

mine are only 480cc but juts seems no matter what i do i cant get it to stop overfueling

Then you have a problem, and it will not matter if you change till MS2

My engine runs lambda 1 at idle with 440cc injectors and v6t46 kent cam

is that on the same mapp as i am running

ok cool before i do any upgrading i have a mate who is coming down so i will see what i can do with it i have it running well on 160cc injectors so im sure i should be able to get ok with 480cc

I don´t remember what map i gave you

it was the start mapp for the 350 cc tfi any chance i get a copy of the mapp you run on your car now and ill try that

give me you mail then

thx mikeal

hi mikael did u get my email
thx rich

You got mail

thanks ever so much its very appreciated i will try this mapp tomorrow if the weather is not raining and i will send you some video s when its going right

thanks mikael

what sort of boost are you running with this mapp

peaks 1.2bar and runs 1.1bar but have tested 1.4 and it´s works on that to, but don´t feel safe running such boost on standard compression and engine

thank mikael love the capri by the way its very tidy car

Thanks

hi mikael well its all good working great i think sits at around 1000 rpm and nice and smooth i just need to set my boost up on it now and my fuel regulator and all should be ok

which version MS is it and how much does it cost when it is complete and I can just do the wiring?
