Thread: MPG?

whats everyone get for mpg?

setup is ve-t, id1000's, n62 maf, ect ect..

cruise afr 14.7, idle afr most of the time is 14.7 sometimes 14.0 sometimes 15.6 depending on if i have my headlights on or rad fan.. accel afr upto about -5 is low to mid 14's, 0 is 13.0 and of course boost is mid 11's

i dont boost all the time and even if i drive totally "normal" i still barely get 21mpg.. however thats mostly in town / partial freeway.. is this about normal for a setup such as mine?

my freakin stock se-r gets 26-28mpg SAME routes and i hammer it all the time lol

This is on my safe tune, running excessive fuel in both cold startup and on WOT

VE-T, 513cc, 3bar MAP
19.12 MPG on last tank (E85) translates into 25.5 MPG with normal 9X octane

It could be improved alot, like removing fuel from cold startup, and using the wideband to cruise at 15.5, but that's something I'll have to look at later. I think it's acceptable at the moment?

Cruising Afr can be leaner than 14.7. Grab an egt sensor and mess with your cruise afr's.

I dont have a wideband yet, but just messing a little with fuel trim from the base VE, 333inj, N60. I'm getting anywhere between 30-32 mpg with mixed city/HW. I had some issues with timing and even then i was getting 28 mpg.

Damn that's pretty good. I think lynch is gonna have problems getting that kind of fuel economy with 1000cc injectors. Nature of the beast really.

My VET 9:1 GTX2867r 20psi mostly city has been getting 21-22 MPG (99' P11 205 tires) and the 02' P11 195 tires auto T25BB 8-9psi has been getting 24 MPG mostly city. Both need fine tuning but run out really well

I was getting a little over 30mpg when i drove from your place to mine. all freeway averaging 75mph, was in narrow band closed loop and afr bounced between 14.2 and 14.7 constantly (normal narrow band behavior) using static thresholds.

I got 32-34 MPG while cruising since I installed Nismotronic in my stock and slow B13.

I got 38mpg on my way too and from the last GA convention in my not - stock slow b13 after installing my AEM and spending a while on the dyno

I def used to get better mpg.. think my injectors play a role in it?
