Are you targeting 14.64? Does the WB equal the LAMBSE? Are you sure you are in CL?

I calculated mine as I went to and from the Restomods car show in Reno Nevada. I got 21mpg on the way there and 22mpg on the way back.

yes that is what I am targeting. I don't have a WB, so I can't compare the 2

I had to adjust my sealevel load scaling to get my load down to the 30-40 which put me in CL and in the 14.64 range.

I read on the tweecer board that the CL fuel table could not be modified. It will always revert back. I have not tried it myself, but again I have not had to modify it yet.

I would bet if your cruise is commanding 14.64 and you are in CL, that maybe spark is not high enough or the actual feedback from the O2's are not really reading 14.64. Also make sure that the adaptive update tabe has positive values in the section fro you cruise load and RPM.

I read the same thing, Clint. I belive THUNDERSTANG was the one who said it was hardwired into the EEC, and not a changeable parameter...

QWKSNKE · 06-10-2005, 09:39 AM

well it shows being changeable. I had changed all of mine last fall (when the blower was installed) to command high 11's - low 12's at 50% load and up. They were still in there when I changed them Wednesday night. We have adjusted the load values some, but I am sure they need to be changed some more.

93Cobra#2771 · 06-10-2005, 10:42 AM

Right. But IIRC, it still doesn't change anything, even though it SHOWS changes are being made. Basically, a dummy table that effects nothing. The CL a/f is HARDWIRED into the EEC (again, this is going from memory)...

86GT · 06-10-2005, 01:26 PM

I don't believe the A/F needs to be that rich at 50% load. I could understand higher loads but not the crusing loads. Crusing loads should have almost no boost. If there is no boost then 14.64 can be targeted. At the crusing loads are you in CL? I did not see that in any of the previous posts.

QWKSNKE · 06-10-2005, 02:53 PM

I should be in CL but I will have to look at Italian LX's datalogs he has done in my car the last 2 days (he commutes 100 miles roundtrip everyday so he has been driving the cobra for datalogging purposes)

you have personal drivers. WOW
