paul mac Posted July 25, 2007 Share Posted July 25, 2007 hmmmm fuel economy and supras ehhhhh dont really go together, well done for moderating your right foot i know its very hard to do Quote Link to comment Share on other sites More sharing options...
suprafan72 Posted July 25, 2007 Author Share Posted July 25, 2007 was just a test really... didnt go on boost at all.. Quote Link to comment Share on other sites More sharing options...
Gord R Posted July 25, 2007 Share Posted July 25, 2007 Amazing what you can get - we got similar out of the T88 off boost going to Oxford Quote Link to comment Share on other sites More sharing options...
Kopite Posted July 25, 2007 Share Posted July 25, 2007 I tried this the other way on a 100 mile round trip, only got 20mpg without boosting at all, 75mph! What sort of AFRs are you getting off boost? Quote Link to comment Share on other sites More sharing options...
Mike B Posted July 25, 2007 Share Posted July 25, 2007 What sort of AFRs are you getting off boost? 95? Quote Link to comment Share on other sites More sharing options...
suprafan72 Posted July 25, 2007 Author Share Posted July 25, 2007 14.7 to 14.8 but i get that part throttle too until i break boost.. Quote Link to comment Share on other sites More sharing options...
Kopite Posted July 25, 2007 Share Posted July 25, 2007 Hmm mine's a bit richer than that (13.5ish), needs more mapping anyway i think Quote Link to comment Share on other sites More sharing options...
suprafan72 Posted July 25, 2007 Author Share Posted July 25, 2007 Hmm mine's a bit richer than that (13.5ish), needs more mapping anyway i think Yeah i agree, you can deff go leaner.... cruise and part throttle..... Quote Link to comment Share on other sites More sharing options...
Kopite Posted July 25, 2007 Share Posted July 25, 2007 Yeah this was only feathering the throttle as I wanted to see the max I could do, had the heaters etc off, windows up etc. Will speak to and see what we can do Quote Link to comment Share on other sites More sharing options...

paul mac Posted July 25, 2007 Share Posted July 25, 2007 14.7 to 14.8 but i get that part throttle too until i break boost.. stoichiometric, not being funny guys but if you aint got this at cruise take it back to the mapper this is absolute basics Quote Link to comment Share on other sites More sharing options...
Kopite Posted July 25, 2007 Share Posted July 25, 2007 What ECU are u running? AEM dude Quote Link to comment Share on other sites More sharing options...
suprafan72 Posted July 25, 2007 Author Share Posted July 25, 2007 stoichiometric, not being funny guys but if you aint got this at cruise take it back to the mapper this is absolute basics Not forgetting that i can cruise between 2 to 3.5k without using any boost at all (just vacumn) even on part throttle.. most smaller singles will start to break boost on part throttle...

Was simply a test to see what it would do, natural curosity.. allso nice to be more effficient off boost as it makes a difference to off boost pull if you get the right air/fuel mix Quote Link to comment Share on other sites More sharing options...
