My Kawasaki ZX7 came from the factory with carbs. I see throttlebodies from GSXRs on eBay constantly. I keep kicking around the idea of buying a set of GSXR TBs and fitting them to my ZX7. Once they're set up properly I'd like to add a turbocharger.

A local guy set my P72 up to control DSM 440cc injectors and boost on my GSR for cheap.

What sensors would I have to fit to the bike's engine so that an OBD1 ecu could control it?

water temp
map
reluctor wheel from the distributor
air temp
tps

Anything else?

Can a Honda ECU read to 11.5k?

Is there any way to control 2 coils or maybe 4?

 

Pretty sure the task may be higher than the gains, but if your in it for the DIY why not.

Have you considered just converting to the whole efi system from the fuel injected bike?

Honda ECU in stock form can only control 1 coil, but there are add on boxes that may allow this possibility.

 

Yeah, I have thought about that and to be honest it's still a possibility. The Honda ECU though, I have most of the parts I'd need already and sensors are as close as the junk yard. Once I get my ECU tuned for 550s I'll have a set of 440s floating around. I have a handful of map sensors, my old CRX pump.

Adapting the throttlebody spacing and fitting the reluctor rings will be the hardest part as I see it.

I've been reading some Megasquirt sites about people who have done similar things.

I think 200hp would be super fun and a blow off valve would take some getting used to.

 

maybe megaquirt?
You will need all the sensor in the Dizzy to make it work on something else.
