it tells me RIGHT when to shift to get the best gas mileage EVAR

hoqw doesd it know so much??!

 

Wich one?
Is it hooked up to the o2 sensor? TPS sensor?

 

He is talking about the jdm cluster "economy shift" light.

 

its JDM its helllaaa smart duuuuu....

 

hm...not sure. Might have something to do with the fact that kat also has a sensor....?

 

its not a jdm anthing. its just a crx with a light on the dash that tells me when to shift.

 

ummm, u need a light to know hwo to get good gas efficiency?

 

its magic man like wizards and ****

 

it is magic!


i think its based on the ELD but not sure.

i got 56mpg last time when i shifted when it told me to!

damn i take back my previous post! i thought u just had a static rpm based light that told u when to shift, lol.

 

might be, usually tells me to shift betwen 1500 and 2000 rpm, give or take 500 dependin... seems like going down a hill i will shift at 1000rpm lol

 

****, I shift at 4000 on normal driving and I get 250 miles to from a full tank.

 

foo i drove the **** out of it on the last tank (105-110 long time near WOT up every hill) and got 370 on the last tank

im aiming for 560+!

 

damn hf's

 

Back in the old days (I remember them all too well), you could buy a gauge that would show you how to get good milage.

They were nothing more than a intake manifold vacume gauge. The idea being that if the manifold vacume stayed within a certain range, the milage was better.

My guess is that the light you are talking about senses at least the MAP sensor, among other things and generates the light.

Whatever it's based off of (MAP, etc...), it's tight as hell. I get around 280mpg on my REX's tank. ****, 370 - I only wish. Where'd you get such a contraption¿ Also, it seems like shifting @ 1500 and 2000 is really low.... could just be my brain not working but it seems like that would put you far out of the power band therfore bogging the engine down and getting worse fuel economy than shifting @ higher RPMs....?

Yeah Alittle light in the cluster..Tells you when to shift to get the best MPG..

Only works though if you have the stock HF ecu..

 

it turns shift light on at peak tq. on stock hf is about 2000 rpms.

BMW's have had them for ever. I remember seein it in my friends car and i was like WTF is that...

 

I bought a 90-91 HF cluster for my 91 Si since my fuel needle was fuxored on the original cluster, and it had a shift light. It obviously didn't work in my car, but it was there.

I think all HF's had that except for California cars. Just like the EG Cx's.
