A regular lambda on a production car is measuring a very narrow range, giving either a lean, ok or rich result (simplified) A wideband lambda can read a complete range and therefore allows you to help tune an engine.

good enough for basic mapping and running closed loop for cats widebands need a seprate controler as thay operate at a totaly diffrent voltage range (some contolers can emulate a narrow band tricking ecus to run a diffrent afr) unless its linked to an ecu thats designed to use it that is |

What have you guys done about re-routing the coolant that normally goes in via the thermostat part of the donor manifold?

I made a housing which has the two sensors in it and bolts onto the exisiting thermostat housing

I though the existing thermostat housing was located on the end of the orginal donor inlet manifold kind of on the front side near cylinder 1?

It is, I'm using bike carbs sohave modified the water outlet

Ah I think I get you now, so you've used the thermostat & housing that was on the bike carbs rather than modifying the donor one to fit onto the bike carbs?

I'm a bit lost with this now. I've got a set of zx6r carbs with tps, the wiring loom from the bike, and a fuel pump. I'm a bit stuck with how to make the manifold as my cvh head has the coolant coming out just behind the 4th cylinder in a sort of large square shaped hole. I'm guessing I need to make a pipe outlet of some kind on the manifold i make and then re-route the coolant out of this pipe into the donor thermostat housing somehow?? There's also a lot of electrical connections on the top & bottom of the donor manifold so do I need any these and if so where do I move them to? Starting to wonder if I've bitten off a bit more than I can chew with this one and maybe should have stuck with chopping up the chassis to make the donor fit as is

Dont be disheartened, its easy! very easy.
You can forget about ALL the electrical connections on the donor manifold if you are going megajolt You dont need the bike loom really apart from the connector that fits the tps and the fuel pump The manifold you need for the carbs should only have holes for the inlet runners, the square coolant outlet needs to be blocked So basically a flat plate with four tubes to match the carb spacing Then you remove the core plugs on the end of the engine and the coolant will flow from here instead via either a 1.6cvh thermostat housing (which fits straight on) or a home made outlet, if you make one weld in a small boss for your water temperature take off Shame i took my cvh out otherwise i would have taken loads of pics for you, i will see what i can find on my laptop |

I found a couple of pics, just keep asking if you are stuck!
