Eco Block from crawford performance

I found change for the first 6 months. Then I think my computer re-learned everything. So, I removed it. I did lose power up hills after removing it though. About the only thing that changed after the fact.

 

Did you disconnect your battery when you installed it and did you have the chip reprogrammed for the air intake?

 

I disconnected the battery when I installed my Eco block and Volant throttle body spacer. I've noticed a difference in bottom end power, throttle response, trans shifting points and mileage.

 

FWIW, I still have mine installed in a Volant intake and still get good milage except I have 35's now. I get better milage than some stock 6 speeds. Was getting 17 mpg with 285's and now I get low 16's with 35's running 33psi which does not help milage.
I was getting 16 mpg stock with no eco block on stock tires. I guess I'm the lucky one that it actually works for.

 

If your speedometer isn't recalibrated for your 35's, then your mpg isn't accurate.

 

Just multiply you're mileage by 1.124 to get correct mileage

Yep that fits the definition alright

 

Sure think smartass, but not everybody wants to shell out the money for a speedo calibration or purchase the device. A simpler way for those that don't is the simple equation.

 

Not sure why panties are in a bunch. All recalibrated means is adjusted for difference in distance traveled per revolution. I don't care how its done, I was just making sure he was not calculating mpg off of stock odometer readings without some form of adjustment. Sorry you didn't see it the same way. No offense was intended.

 

Sarcasm brother, purely sarcasm bro. Bad thing about the net is it's impossible to detect the tone from words typed. I actually laughed when I read what you posted. Not offended here bro.

Larger tires mean you're traveling more distance than what the odometer reads, so there is a simple calculation to figure what your actual mileage is with the larger tired. Yes it's more accurate to have your speedo recalibrated or get the speed healer, but for those that don't have the funds, they can use the calculation to get a more accurate account of their miles traveled.

 

I know this man. I know exactly how much my speedo is off. The mpg I posted is the corrected mpg calculated with 35's.

 

Pretty good then if your getting about what you got stock with 35's

 

I was using 1.11 to be conservative. If I use yours, I would be posting even better milage.

 

Yeah, I'm very satisfied with how my truck is running regeared with 35's. I ran overgeared on 33's for a little while and was getting around 14.5 mpg.

 

I only get good mpg's if there's a stiff tailwind running down a steep grade on a high gravity day.

 

lol. When I was getting bad mpg when I was overgeared I thought that was it and it was going to be worse with 35's, but the bigger tires brought me a little closer back to stock gearing and it got better. I am still a little overgeared, but that helps turn the 35's easier while cruising in 6th.

 

What's your gearing? I was running 285's then stepped up to 315's with 4.56 gears. Now Currie F9 with 5.00 gears. I'll see how the mileage is once the truck is finished lol

 

Jealous, I want a Currie rock jock60

 

I'm running 4.56 gears but I'm a manual so I have a lower final gear ratio. But, I think it's perfect a little lower for the heavier 35's.
