Am seriously thinking about using an Ignatech unit on my big-bore (944) '94 900 engine, and was wondering whether or not to order either a TPS unit to it or an air flow sensor to go with it.
Do either of these extras (TPS and AFS) help, or is just the IgnaTech unit happy to run without ?
Engine will be running with K&N filters on 39mm FCRs and a free-flowing (open
) exhaust.
