evening all,

i have been thinking about converting my pinto with r1 carbs over to r1 throttle bodies and ecu system for a few months, but im struggling on where to start and what im going to need, i have been researching all day and reading many texts about map sensors,tps sensors, water and air temp sendors etc etc etc and im just getting lost. what ecu system to i use, i looked at the omex website and there are 3 different kits, which each contain 5 or 6 different sensors, where do i start.

can any of you help and break it down into simple english, for someone who is not a engine techy by trade.

cheers alex

Minimum information the ECU needs to fuel and spark. Crank position sensor for engine speed and position. Throttle position sensor or Manifold absolute pressure sensor for load. Coolant temperature sensor and air temperature sensor and you can run a basic batch or semi-sequential injected system.
You can add more like lambda sensor, knock sensor, barometric pressure sensor, road speed sensor, cam sensor which will all allow further fine tuning but you don't have to have them. If you were going with Omex then you would use the OMEM600.

Hi there,
Im guessing that a distributor based setup, if so then if your starting out on the EFI road Id do fuel only and leave the distributor in place. We can then trigger the ECU from the coil -ve, this means you dont need to add any trigger wheels and crank sensor, etc, also you can simply start by tuning fuel and not worry about spark timing at the same time.

When youve got fuel cracked you can then you can go over to spark as well if you wish, there are a few options then, but no need to confuse everything now.
See my site here for info on MS ECUs and a glossary of terms that may help:

Youll need an Air temp sensor for the ECU to work out the density of the air, youll need a coolant sensor for the ECU to add fuel when the engine is cold. Youll need a lambda sensor so you can tell whats going on with the fuel air mixture. (this is basically your feedback)
A TPS is also needed if your running throttle bodies, this will tell the ECU what load the engine is under.
The temp sensors are easy to get hold of from scrap yards, etc. A TPS should be on your throttle bodies already. Thats all you really need apart from the obvious injectors, fuel pressure reg, fuel rail, etc,

phil is that you i met at stonliegh last year when you parked you cobra on the mk stand over night?

phil where is your company based, i was thinking about these injection throttle bodies for the DAX, i have a custom made stainless manifold for the R1 carbs, do you know if i could use the same manifold in the R6 throttle boddies.

Hi there,
no, wasnt me if the car was parked over night, I did go but didnt leave the car.

As for the ITBs, as long as they are the same size then they should be OK, it all depends on how they fit, the gap between them and head room, etc, but Im sure with a little modification they could be used.

i think that they are the same size, i cant see why yamaha would change something like that,looks like map sensor is included as well which is a bonus,
