Tell us how you go with that power supply. Its looks good. How hard is it to put together, does it come with a preprinted board or do you have to make this yourself.

Mileage, havent checked it out but the stock factory tune gave me around 400-450km a tank on a set route. With programable EMS and tuning around the 15 to 15.5:1 A/F ratio gave me a solid 600km per tank on the same route. With the new injectors and coil voltage I see an easy 50km extra on that route but need to check. For me its not just economy, its the improved drivability,idle and tunabiliy. The tuning window has opened up heaps and made it so much easier to tune. Cold starts are so much better (minimal temp compensation as compared to previously), the car is alot better to drive.

Re: wideband, I have a Innovate LC-1 I bought a couple of years ago but couldnt get to work on my EMS8860 at the time. Once I get this working I will be able to measure 22:1 on my laptop

Other things I am going to do are heating the fuel via coolant and making up a good oil/air seperator for the crankcase vapours to pass thru before going back into the intake. Neither are going to increase economy on its own but with tuning will allow me to push this lean burn to the limit. This engine I am experimenting on has done 330000km and has a bit of blowby and oil in the throttle body so a well built oil/air seperater (not just a can) will help.
