Trigger Patterns

[alex_blue16v]

Basically im after some info on the trigger patterns of the F4R engine as i am using one on my mk1 turbo conversion. Ive been informed that it runs a 60-1 pattern.

the thing is the standalone ecu im after recognises the standard 60-2 or 36-1 patterns and was wondering if anyone had overcome this problem and if so how, or are there other ecus out that there that recognise the 60-1 pattern.

many thanks
alex

it uses "effectivly" a 60-2

which ecu?

 

[iimushroomzii]

You need a megane flywheel and clutch which uses a 60-2 pattern iirc.

same as a 172

What's a trigger pattern?

 

[dunlop]

what the crank sensor reads to know where the crank is intime to fire the coil and injectors

cheers for the replys guys, as you say it is 60-2 so it will work with my ecu, i got my numbers muddled up somewhere.

Im using go-tech MFI pro as a mate of mine was running a similar setup on his rs turbo with good results and he can get trade discount for me.

ive managed to sort myself a flywheel and now im looking into clutches, any ideas where to get a good paddle clutch, ive had a look at the yozzasport one but there is no torque rating on it?

cheers

all the "big tuners" use the helix grp A one, same as in the cup racers, its good for 300bhp and 250lbft IIRC there is also the Alcon clutch, but they're not as reliable

at yozza (when i was still envolved) we used the helix for 10K miles and only had 0.2mm wear on the friction plate

there is a grpA unit availbe from valeo and quater master

 

[alex_blue16v]

cheers bud, helix one sounds like the one for me then.

 

[Fred@BTM]

aye does the job fine

What's the difference between 60-1, 60-2 and 36-1?

Basic description will suffice, im logical enough

 

[dunlop]

theres only 36-1 or 60-2

one gives more info as to the position of the crank.

so the ones running 60-2 will usually be running sequential/semi-sequential injection and wasted spark ignition.

the 36-1 will run a dizzy and batch fire injection

 

[AstoN]

36-1 will be less economical and older i'm guessing.

 

[sideways danny]

36-1 will be less economical and older i'm guessing.

makes no difference at all

 

[AstoN]

i guess i guessed wrong lol. Just with the batch fire injection sounded less economical and distributors i thoght were only used on the older stuff. newer cars have these stupid coil packs which are far too nervous.

 

[Andy GDI]

36-1 will run fully sequential as well...

for sequential you need a cam sensor as well.

 

[dunlop]

172 runs semi-sequential.
they don't run a cam sensor. or do you mean if you run a 36-1 setup?

 

[broster@JAM-Sport]

you can run 36-1 and if you have a cam sensor you can still run full sequential.
