A few minutes ago I mounted the commander to the power fc and drove a while..
the speedo showed exactly 100km/h, commander exactly 95 km/h.

It`s cold aoutside and I have stock rims with stock sized winter tires..

Wtf, that`s 5% difference.

 

Ehhhh.... 5% is very normal.... But are you sure the commander is accurate.
You need GPS or radar or something else to measure the real speed....

I`m not sure... Peeps speak of 2% but 5 percent is a lot IMHO


It`s the same with the revs... tach sais 4100, commander sais 3800.... damn
I knew that they`re way off, but I didn`t think that major.

 

Sounds normal too. My VTEC engages at 6000 rpm (5700 in real).....

 

I'm pretty sure it's normal. 5k'm isn't that big of a difference. The tach is also off too. What a bummer. I wonder why Honda let something like this go?

 

since you have a tool that will tell you the exact rpm & speed, just pull off the needles and put it back on.

yshi - who finally fixed his fuel gage over the weekend; no more guessing

 

If it wasn't VTEC (at 5700 rpm) I wouldn't have know how far it was off.....

 

I just went by a couple of those speed limit/radar signs this morning, and it (the speedo) was off by almost 3mph @ 40 and 4-5 mph @ an indicated 60 (radar sign at first said 56, but then flickeded as we went by and displayed 55 ... mph).

This was on 205/50/15 Asenis on stock ITR wheels.

Sort of explains why I'm not getting pulled over for speeding lately!
Especially when I've thought I must have been doing at least 20 over.

 

OK... my speedometer needle stops at 140mph but the car still gaining speed... one time when i got pulled over one of the officers said that my car matched the description of the yellow acura going in excess of 140mph ...

 

only 300 rpms? When my stock tach reads 9100 my VAFC is telling me its 8500

 

Ive noticed the tach gets more off the higher the RPMS.

 

Yes ofcourse, the difference is a percentage not an absolute value (like 300 rpm or something). It's about 300/6000 x 100% = 5%. Hey, I saw this figure before!!!

 

You are one girl with *****!!!

 

Notice that she didn't say anything about getting a ticket!
Let me guess, ... a blonde?
No WAY would she be driving that fast, it must have been some "street racer"... hahaha!

 

And god said: "Brain is off stock..... give `em **** now" j/k

 

The Speedo on my car vs. what I see on the PowerFC are pretty much the same, I would believe that they would be exactly the same considering the speedo is electric, and it runs through the ecu...now the rpm...well they are off by about 200 @ indicated 8800 rpm, ie. it reads 9000 when it's 8800 rpm.
