Pics of boost gauge

[HeavyH20]

I just use the DashHawk. It is a realtime monitor, resets codes, monitors spark retard, fuel pressure, etc. 144 or so different functions. Nice little utility device. Also measures 0-60 performance and 1/4 mile.

The Dashhawk provides accurate boost pressure from just the OBDII port?

Yup, it measures vacuum pressure via the sensor that the ECU uses. So, what the engine sees, this device sees.

Are you saying that you can takeoff faster with TCS on?

I haven't really had the chance to experiment with it.

It is only good for the first 18 mph, but it does allow a little wheelspin. I found it helped. So much so, that I was able to get a low 6.0 second 0-60.

So for the best acceleration:

TCS off
Brake torque the engine to ????rpm
pedal to the metal in Auto Or Manual? Shift points?

I was just reading the thread about the new 300hp Caliber SRT-4 and they rated that at 5.9 seconds 0-60. 6.02 for the CX-7 is great!(friday)

HeavyH2O, what mods are on your CX7. I can't believe a stock CX7 will do low 6 0-60 times. All the car magazines reported high 7's at best.

Will the DashHawk give any trip info like MPG, DTE, etc?

I know, HUGE difference. The car has no mods other than yanking the baffle out of the air box. I was baselining the car before I bought all the CP-E parts. If I put it in drive and simply floor it, 7.9 to 8.1. I think that is what the magazines report. After the new ECU flash it is now 7.5 doing the same thing. If I shift early, manually, instead of in Drive, I can get 6.7 - 6.8, easily, with a normal launch. If I load the trans before take off (2200 rpm), TCS off, and really watch the RPM's, a low 6 second is repeatable anywhere from 6.2 to 6.4. The 6.02 was things coming together just right. Cool air, good launch, the right shifts, etc. The real secret if NOT flooring out of the start. That seems to fatten the fuel delivery too much. Instead, do 3/4 until you feel the turbo pull, then push it the rest of the way. That part is good for .4 all by itself.

Of course, it is nothing like my old Grand National that did 11.8 1/4 mile times. Couldn't turn worth beans, however. 0-60 in 3.6

Well, I find that car mags report things a little slower than they are capable. For example the MazdaSpeed 6 was tested at 6.2 seconds. There are more than a few members who have easily eclipsed that number. So, the Caliber is likely a low 5 second car in the right hands. That will likely whoop me to 60 by a second or more. And, it should, with more horspower in a smaller vehicle!

I will test those functions and report back. If the computer reports them, then they should be available.

I checked the mileage functions, and it appears that the computer does send the mileage information. I suspect that the US cars do not have this function and the metric cars will since the US is the sole country still on the old system. Any non-US users to verify?
