damn nice, 145 hp and 500 miles per tank :shocked: thats nice :TU:
interesting; getting more mpg than a stock powerplant designed with fuel economy in mind (stock b7; 35-41 highway, manual), but making 40 some more hp...which obviously requires more fuel...

you'd think a stock honda would be the epitome of efficiency.

Why would you want to run the vtec ecu over non? in a non-vtec engine
1) 300 rpm higher fuel cut, 6500 vs. 6800 with CEL 22
2) no speed limiter
3) P06 ecu out getting chipped

do you use a wideband to tune your fuel settings? just curious ...

i'm thinking you've got the fuel values tuned leaner than stock to get that high mpg.
retarding it a bit more than usual perhaps? this is very odd... will your catalyst melt? hmmm...

I want that kinda gas mileage. :( I'm getting 22mpg, ~220 miles on a tank, driving it almost to empty.

My car has yet to be wideband tuned, just my oldschool (V8) knowledge. Right now the A6 cam is 1/2 tooth retarded and once cam is dialed in correctly with a adjustablbe cam gear, I fully expect mileage to jump from 43 mpg highway to 47-48 mpg highway. Then I'd only need 10.5 gallons or so (11.9 gallon tank) to get my 500 miles per tank goal. With the cold weather, it's not gonna happen till March or so due to the warm up times of the engine.

93sohcvtec, shitcan the skunk2 program as it is for a high compression LS/GSR motor and has no place on a SOHC tune.

I guess about 40 psi, vacuum line on at idle.

ECU will adjust injector pulse width though thru short term/long term fuel tables.

Is there another program that you would recommend?

I had figured as much as far as what kinda engine it was meant for... But it runs sooo much better and has a lot more power with this program. :(

It's my skunk2 ecu. It runs rich as all hell, but it's got a crapload of power for not being custom tuned, 100X better than stock... I just need to get on a dyno and tune it properly... Or get my friend to stick his wideband on it.

kill the $5 skuckass chip, get a real SOHC chip.
It's just a simple program on a flash rom chip that I had thrown on there when I got the new ECU. I just need to get the chip reprogrammed. The problem is that the place that I had program the first one has gone out of business, so I need to track down the owner. He has a wideband o2 and crap so he can make a chip designed for my engine. It won't be dyno tuning, but it will be pretty damn close.
