I just got mine, it didnt come with the owners manual...i need help big time...when you start it up it give you a couple options

Ford
gmc durmax
chrysler
chevy
other

Since mazda is a ford company do you go to ford...


HELP me...i want to kill the guy i bought it from on ebay
 
alright it's seems to be working under ford, but the rpms are a little off...is it possible that the stock rpm is off
 
If it is asking you what car you own then it is not working right. It should recognize your car from the info its getting off of the CAN bus. Make sure that you have your car started before you first plug it in. Once your car is running and its plugged in, it will start and shut down with the car.

If you have any issues goto the msd forums like mentioned above.
 
what the... mine never asked me about my car. did yours come with a cd and the usb cable.

It will ask you which car if you plug it in while the ignition is off. Its because the CAN bus is providing power but not communication so the DashHawk thinks its an unknown manufacturer.

Anyways version 2.3 is out on the dashhawk website (www.dashhawk.com). Its much better than 2.2.
 
I have dealt with MSD customer support before and they are AWESOME!!!!!

They are always willing to assist you in any way, shape or form. Don't hesitate to call, e-mail or harass them. They are great!
 
jay07ms3 - what makes 2.3 better than 2.2? I looked at the website and didn't notice much difference in the release notes

The biggest improvement IMO is the multiple logs. You can now store up to 5 data logs, 0-60 logs, and 1/4 mile logs.

Another improvement is the button response. Its still not perfect but it responds better than 2.2. Now if you been keeping up with the Beta version on the tech forums then 2.3 isn't that big of an update from beta 10. But from 2.2 release to 2.3 release, its definitely worth it. And why not, since it only takes a few minutes ;)
 
i checked out the dashhawk... a few questions for the MS3, and thanks for the info.

Q. Do you need another piece of hardware to get the a/f ratio or is it out of the box ready with the most recent betas?

Q. Does it display egt's or does that require a sensor welded into the downpipe to be connected to the factory harness?

Q. I read on the msd website that the dashhawk gives three different air intake temps, what are the locations for these?

Q. Has anyone with an ic and/or air intake upgrade seen lower air intake temps?

Q. Does it provide trans, oil temp, and all of the ford specific numbers mentioned on the parameter section of the msd website?

Q. How comes i havent heard any of you msd owners rave about this awesome product?

I numbered the questions to make it easier to read, hope you dont mind

1 - it read a/f equivalent, someone said multiply by 14.7, this is correct and I understand that you can set up the graph when you view the datalog on the the computer to automatically multiply it. I believe I remember seeing that they are going to add a/f soon

2 - I haven't looked at egts lately, but it does give you cat temps and I think its the same thing, not sure

3 - I only have one air intake temp. Remember that the dashhawk is designed for many different vehicles and may or may not support certain parameters depending on your vehicle

4 - I have the cobb SRI and while I haven't data logged the info, I have noticed a difference as I do monitor AIT and I can't say I'm getting cooler than stock because I didn't pay too much attention with stock intake. But I can say that at about 30 mph I see AITs about 5-6 above ambient temp

5 - Don't know, havent checked

6 - I really haven't tested it to its full potential, haven't had a chance to use it more than as a shift light, still haven't checked out the data log potential or performance metering capabilities. I live in a city and don't have any open stretches around to really open up the car without mr police officer stopping by to say hi

hope this helps...

^^^ Thats because you haven't searched very well ;) j/k
I've made quite a few posts about this amazing little gadget but here is the most detail.

And everyone else answered your questions pretty well. As for the Ford PID's, I don't think we can read those but I haven't actually tried to.

The intake temp sensor I believe is after the turbo and the IC but I'm not 100% sure. I'm basing this off of certain logs I've made (heres one done on a dyno). The temps went up pretty drastically during the run. I don't normally see this type of increase during normal WOT driving. And if it was before the IC, the temps would be a LOT higher.

And you need a separate EGT probe for EGT's. And even then, you can't hook it up to the DH until the Hawkeye is release which should be soon. Check out the MSD forums for more on that.

As for the accuracy of the AFR readings, its as accurate as any wideband O2 readings. The ECU converts the sensors 0-5V reading into a Lambda reading. It says its the equivalency ratio but its wrong. Lambda = 1/EqR and MSD is currently fixing that right now. As of the latest firmware beta, the DH now read AFR's but the readings are wrong since the math is based off of EqR's not lambda readings. But all AFR readings from WB O2 sensors do exactly the same math. All readings start off as a 0-5V signal and get converted from there. My dyno run readings were just about dead on with the shop's AFR readings, except their sensor couldn't read below 10:1 like mine could :D

my MS CAI reads IAT 2-3 degres above ambiant and i think temp sensor is before turbo beacuse even after intercooling it is still over ambient and i havnt seen any temp sensors after turbo. i belive temp sensor is in that pancake looking thing inbetween CAi and turbo.
