S2000 engine/F20C crank trigger wheel
Rocket_Rabbit - 19/6/13 at 07:47 PM

I know the F20C has a poxy 12 point CTW and that this will cause problems for aftermarket ECUs.

Has anyone tackled this problem before?

Can you simply get a new trigger wheel made (36-1) and replace the oem or mount the new one to the crank pulley?

Thanks

Omex and emerald can run on the standard trigger wheel, im using omex 710

Only the Omex 710 can run the standard trigger wheel, the 600 can't

The ECU's that can run the standard trigger wheel tend to be able to program the teeth number. the Omex 600 has a set number of options

Also, to run the S2000 with an Omex 600, you'd need to convert to a coil pack (as opposed to coil on plug). With the 710 you don't need to do this

Omex 710 is quite expensive mind - £1000!

I was looking at using the Canems ECU which does state 36-1 or 60-2

If you get a 2006+ engine then you could look into the honda data ecu

Use standard harness then too

It's all do-able. Just depends on how much you want to spend vs how much work you want to put into it really

Also what hasn't been pointed out is that you can actually use the standard ecu. If you're going to the trouble of converting from coil on plug to a coil pack, then you may as well read up on how to use the standard ECU. A few people have done it on here I think and say it isn't a hard job

A DTA S60 is about £750 if the budget would stretch a little...

The OEM ECU is a waste of time TBH and anything with a DBW throttle is a non starter!

... and runs with all the standard sensors...

Fair enough! Seems like D60 is the way forward. Pete, did you bother connecting the cam sensors too?


PeteS2k - 25/6/13 at 12:32 PM

The DTA S60Pro just reads the exhaust cam sensor. The only watch point I found was a bit of inconsistency with polarity of sensors between the Honda wiring diagram and the DTA - or it may have been my cack-handed putting it all together! I can't remember which ones now, but I do remember playing around with MAP, cam and crank sensor wiring until I got it running smoothly. The diagnostics on the DTASwin software made it a pretty straightforward job to work out where the problems were.

I also couldn't get the IACV to work, but others have, so again probably me.

There's a map with the unit for a F20C on std intake and sensors which got me through IVA and on the road by just running closed loop at low revs for emissions.

Some folk have also had success with Emerald, including running with standard sensors. I think they may even be able to supply a map as a good basis to start with, too, these days.

You'll only need the cam sensor if you want to run sequential ignition/injection. At the moment I haven't decided either way, as it's a toss up between an easier life for the coils and running out of wiring pins on my bulkhead connectors

Thanks Pete - I may be calling on you in a few months time!!! I know the F20C pretty well but I have no clue on the DTA

Of course, you're being stalked ;D
