Yes I'm stock 74/155 - supposedly 14.5psi MAP out of the box 12 years and 80k miles ago (when new).
After seeing the previous graph I posted, I don't have a problem with the TorquePro MAP readings - 14.5psi at 5,861rpm WOT. A Little surprising after all those years of use.

They are after all, readings coming from the ECU, whereas an aftermarket boost gauge is another entity all together. As long as the MAP instrument itself is okay - readings should be okay - me thinks.
I'm happy.


Aside - the swings in Mani psi observed also lends question to the Accordion Effect provided by the coolant systems expansion/contraction and it's implied stress on the walls of the intercooler. The unavoidable mani pressure swings shown here are as large, if not larger than those, and much more frequent.

 

Now I gotta work out the namesake of this app - A Torque/Dyno Curve.

I'm not quite sure how TorquePro works out the Torque other than ....
............[Delta Speed / Delta Time] = Acceleration ....Acceleration x Mass of Car = Force

From Force it somehow calculates Nm Torque.
But for me to calculate Torque from acceleration I have to put in my Wheel radius of 0.33m.
TorquePro doesn't know my wheel radius.?????

More pickies.....

A couple of things.....

1) The cfm intake volume is a bit screwed - it reckons its cfm, but hmmm, dont know a car that does 350bhp and 2000cfm - that doesnt follow the 150cfm/100bhp rule......

2) The fuel flow rate - I almost believe that - 1700cc/min at WOT divided by 6 cylinders = 283cc/min/injector - very reasonable

3) the relation between cfm and fuel is "almost expected", but I dont believe this is so perfect - so I'm guessing one is derived from the other - hence the straight line,
but it aint [14.7 x grams/min of fuel ] = grams/min of air.

4) My AIT isnt coming down as expected - so gotta look at my IC Coolant Pump

I've got a heap of other stuff but don't wanna bore the pants off anyone......

 

bumped for twice baked.
haven't viewed your vid yet (monthly bandwidth issues - too much ****....ha!) but soundz cool.
I believe TorquePro has a google maps upload display and video capture add on widgets as well, but above and beyond for me....

l8tr....one of the deficiencies of OBDII wireless I'm using is update frequency. I'm only getting speed at ~1second intervals etc.
Tried limiting the number of things being logged - not much improvement (if any).
Apparently if you pay top dollar for your wireless OBDII plug in - things can get better....
....but I recall looking at someone's Zeitronix .csv data log 12 months ago and seeing speed only change every second or so. So I emailed Zeitronix and got..."OBDII is not a performance port - its a monitoring port".

 

a) The PCM is a computer and a not-very-fast one (anyone know what it is e.q. Motorolla, Hitachi, etc.)


b) OBD-II is a serial data stream, Chrysler uses ISO 9141-2 which has a 10.4 kbaud (~56,000b/s about the same as a high speed phone modem on its best day. In comparison my cable signal to the house is 45 Mb/s ). May be slow to some but beats rolling a Brush recorder chart down a long hallway six ways from Sunday.


c) I think the steady O2 reading is really the one downstream of the cat (bank X sensor 2). It is supposed to measure the efficiency of the cat and once the cat lights off, it shouldn't vary much from .5v.


d) For Android the best home choice is Torque Pro hands down. Lots of add-ons. If you use Windows or iOS, I use TouchScan which is available for all three. If you want to get serious about it, AutoEnginuity will set you back $500 with the Chrysler add-on but if you need to see the HVAC blend door operation, that's the way to go.


e) for $11, I just leave BT dongles in my cars, saves fumbling around.


f) More than you wanted to know.

 

yes - same here, although someone said to me - don't leave them in if you're putting your car into storage as their parasitic drain can be large = dead battery.
I have no info on the validity of such a claim, but I know the stock drain from just the car itself is not small.

Be good if there was a micro USB I/O interface out there so you could "add" I's (eg: EGT/AFR) and output O's to do some relays.

Any car I am not driving has a little 50ma "float" charger onnit. Have never had a ded battery (almost all are AGM now).
