Dual Port Wastegate

Does it fit into the hole where the normal lambda sensor goes? (mine has a bung in the exhaust there, instead of a sensor)

When I was going to run my 20v turbo Derby I was thinking about using MegaSquirt. They sell Wideband O2 sensors at a good price. See the link below, what do you guys think?

A wideband will fit into the collett where the OE one goes (or is plugged) but it won't work as that point gets too hot for the 5-wire wideband sensor to work. It needs to go where Paul described, just where the exhaust goes horizontal. It should also be angled down about 10 degrees. There is enough room to fit one (a Bosch one at least) between the exhaust and the chassis leg and run the wire in the corner between the leg and the floor.

Just buy a Bosch sensor if you have something to run it (there are probably only 2 or 3 types and they are all do the same). I have an Innovate setup and the sensor died (probably either run with the heater on and engine off, or engine on and heater off - best to wire it via the fuel pump relay so it can only run when the engine is running rather than via the ignition or a separate switch). The replacement cost about £100 from the local Bosch fuel systems agent.

I also decided on an innovate but as I have only got the bung fitted so far cant really report on it - came in a nice box and looks good Mike at Vittesse can sometimes get a good price on them - though mine came from elsewhere,

The Vittesse kit can run in either open or closed loop. if you want to run it in closed loop and you have a car that doesn't have a lambda sensor then the piggy back kit can take the raw wideband signal and run wideband from that.

I've got an Innovate as well, and only got as far as having the bung welded in.

I don't know whether or not to bother with the piggy back right now. Can do without the extra expense and is a bit trickier to fit than the MAF kit. I guess on a standard turbo and engine Johns out-of-the-box settings will be fine. I think i'll leave the piggy back (and his new V-Flex system) for a later upgrade. I'd also be interested to see what changes the MAF kit makes on its own.
