whts the dash hawk do?

Its crap, don't buy one
I had one and sent it back.
It supposed to do
Oil pressure = it don't
Oil temp = it don't
Fuel pressure = it don't
Manifold Absolute Pressure = it don't

It does what you state it does not but you
have to have the transducers to support it.
No oil pressure transducer on the engine =s no reading.
No oil temp sensor =s no reading.
No fuel pressure transducer =s no reading
My version 2 DashHawk has MAP. Not sure
what your problem with displaying MAP was.
I have a V6 with very few guages and the MSD
DashHawk filled in for the missing guages.
Mine was also free so you cant beat that.
A co-workereBayed it for his Ram truck and
it was not supported so I got it instead.

I have my Raptor shift light set for 5100 and light it reguarly.
My MSD DashHawk indicates the shift point at just under
red line. Casual driving I shift about 4000.
The owners manual shows shift points for maximum MPG.

Ok I cracked the black book. Gives mpg shift but not rpm's:
1-2 11 mph
2-3 19 mph
3-4 30 mph
4-5 40 mph

I'm looking at the 2005 owner's guide. 3.55 were stock. This chart applies to my 4.10's better.[8D]
