Hi guys just joined up, I don't own an escort but I'm putting. a gti lump in my ka(dont laugh at me lol) basically i wanna put bike carbs on it. ive been looking at some posts on here and found out I don't need management or anything thanks to Stu, I no I need a regulator and emissions arent a problem ;-). I just wondered what u would doc with the MAF sensor really. Cheers guys

Hi and welcome to EVO.

We have various sections here so ill move this for you.

Unplug it and forget about it.... its will be useless on the setup your doing anyway

You wouldn't use the MAF sensor at all with bike carbs.

Oh ok is that because the A/F mixture is set by screws. would that not make it run lumpy then or would rolling road set up sort that. Thanks 4 replies.

Fuel and spark are two seperate things. They just happen to be controlled by the same ECU from the factory. If you are using carbs, then you no longer require electronic control for it, but you still need spark control, hence you retain the ECU for that purpose!

Or you can use external EDIS4 which is completely standalone.You need the EDIS4 module,the sensor on the flywheel and the coilpack.Nothing more.Then you completely eliminate the need for ECU if you don't use it for fuelling purposes.

The ECU sends the EDIS module spark advance information - SAW - so if you do away with the ECU then you'll end up with fixed spark timing.

Perhaps Georgio is confusing ESC-I with EDIS.

Hello people No,I am talking about EDIS4,indeed,without ecu you will be on fixed ignition,which it is 8 or 10 degrees,I can't recall what is correct now.It's a start,although keep in mind that Fiesta RST for example works on fixed ignition timing,ECU is not connected to the corresponding pin on the EDIS module and works fine.Of-course turbo is different application from a NA engine,so you will need advance.For a start i believe it will be fine,only trouble will be a flat spot when you floor it.

It's 10 deg BTDC and would be horrific on a n/a engine. Sure, on a turbo engine it'd be 'ok' on boost but that's about it. You're getting close to valve melting territory at that spark angle.

Thanks 4 replies fellas much appreciated I new I would found somewhere to get the info i need. Got another question though, should I get carbs with tpscif so why? Thanks guys

What is tpscif?

I get tps stands for throttle position sensor,cif...?If you use bike carbs you don't need tps.It is for injection management.

 

Stu,when you say that i get close to valve melting territory on that angle,do you mean under boost,or under atmo conditions?Since I can't alter ignition advance as the Ford management is,how can you overide that obstacle?Pin 3 on EDIS which is for altering advance is not connected to ECU's from what I've seen on wirring diagrams... Am I wrong?...do you know something different...?

 

Sorry for the thread hi-jack...

You can use megajolt/megasquirt to control EDIS.
