Project 40MPG TSi

[KGB Pilot125]

Anyone think its possible? I have never driven a turbo FWD before but I have a spare 93 2.0 FWD just sitting on the side of the house. Its in great shape both inside and out only problem is it broke a timing belt I picked it up for 500 bucks to rip out the intierior and the wiperless wing for my 91 AWD but now that I gave it to my sister for a winter beater I am kinda missing working on a DSM. This might be a total waste of time but I get paid .485 cents a mile for work and drive close to 40k miles a year. If this can get close to 40 that would be twice as good as my 4runner. EPA estimates the 93 gets 26 but they also esimate my AWD gets 26 so something isnt right. I have recorded a best of 30.4 in my AWD and an average over 3 months of 27. this is all with no tunning tools. and on the dyno the AF never went above 11.1

Thoughts, critisism, praise?

i got faith in 40mpg!
why do people say its impossible if it has been done before.

True, i haven't seen 40 on a DSM yet, but i've seen very close to it. At least on highway miles, I dont' think it would be possible in city traffic unless you were running the T-2tiny and had the A/F's dialed down on the lean side. I am still very interested in this whole idea. I've been thinking about trying to come up with a way to allow me to run 2 different closed loop configs on my haltech, but so far i'm not gettng anywhere unless i were to send the unit back and have the firmware custom programmed to allow the use of 2 outputs as closed loop systems.

I would like one that under medium load could keep teh A/F's about 14:1 and the other under highway loads to go about about 20:1. Honda already uses an idea just like this on some of their "lean burn" cars. where they reach readings of 19 - 22:1 under warm up and light load cruising. There's even some saturns ( i thnk it was some of the 96 - 98 wagons ) that run a 5 wire bosch wideband fom the factory for their version of "lean burn" to be able to go a lot leaner on light loads and during warmup and be accurate about it.

Well, i'm off to my final interview with the post office and to take the piss test.. If i get this job i can finally shut down or sell off my construction/painting business and let some one else wreck their bones/joints all year long I'll still run my Tuning and Fab business becasue i love doing that and it doens't kill my back that i still need another operation on.

little update I am scrapping the FWD idea, just couldnt bring myself to build up a FWD (when AWD is avaliable) especially with the amount of snow I travel through. So I have switched to a TSi AWD platform,

Yeah, with the snow, AWD will be better for you anyway.

I think it would be more of a challenge on an AWD but it should still be fun and fun to drive when you are done. Good luck to you though!
