ok all sorted ! DASH working fine..was my bad, didnt understand the process correctly in scannerpro...live and learn thats what forums all about

thanks to all who helped and pointed me in right direction

yes i know how to add gauges in TP RT v5 but in scannerpro when i try add item the item box is blanked out and no choices appear to choose which item i want to assign the new gauge to. I want to create new analogue gauges not right click on the analogue gauge which is in scannerpro already You obvi...

thanks for that tip..good to know

pbusanga

Are you trying to add a new gauge or change the item that appears in an existing gauge? In ScannerPro if you want to change the item that appears in an existing gauge, right click on the gauge and a list of items should appear. What version of ScannerPro do you have? Charles I have version 0.05.057...

i think i have found problem.. i edited the dash and added some new calculated values (oil pressure etc) but i used TP to do the editing. When i use this adx file in scannerpro it causes the erratic behaviour. NOW if i do the exact same editing to the dash and values but using scannerpro to do the e...

that looks close enough...thanks for that, will give it a try

VOLTS , PSI
0.5 , 0
1.2 , 10
1.65 , 20
2.2 , 30
2.75 , 40
3.45, 50
3.9 , 60
4.6 , 70

given this data can anyone derive the formula relating v to PSI i calculated the correlation which is 0.998930946 so there is very close relationship between these numbers

was told by Bob at MEFIBURN that TunerproRT will not work with mefi4.adx unless is modified (not sure if he meant modify tunerpro or adx) On my version of scannerpro i cannot add gauges to my dash there is no way to add a new item. the item box is blanked out in grey. on tunerproRT you click on the ...

pbusanga

Anybody know how to add new gauges to scannerpro..i know how to do in tunerproRT. Really wish my mefi4.adx would work in tunerproRT. Anybody know how to modify it to work ?

pbusanga

Hi Charles, have updated thread in new thread here : http://forum.tunerpro.net/viewtopic.php?t=2896 seems tunerproRT v5 does not work with mefi4.adx files for scanning, or at least i cant get mine to connect even though ports are set correctly. i am using scannerpro please see my new thread re this....

pbusanga

Make sure that you do not have the cable routed near the distributor or any of the spark plug wires. Are you using a true serial cable or the USB cable from MEFIBurn? If you are using the MEFIBurn USB cable, did you install their driver? If you are using a true serial cable does your computer have ...

I asked this in another thread but realized i said data was jumping in TunerproRT, i confused myself, data is jumping in scannerpro and NOT connecting at all with V5 TunerproRT. Sorry for confusion, too many late nights. Am using MEFIBURN SCAN software and mefi4.adx defenition data is jumping all ov...

pbusanga

ok understood. I have only the mefi4.adx file from MEFIBURN as i only wanted to scan for engine faults not modify engine.

So this adx file will not work with tunerpro RT v5 ? and i have to use scannerpro ?

this is what i thought...anybody know the commands for mefi4.adx to run fuel pump ?

pbusanga

went into edit def and clicked on commands then opened reply mode 8 stop chatter and increased body size (Dec) from 3 to 4...is this what u mean ?

Thanks for help,

could you explain further i don't understand , am new to all this

pbusanga

the connection says is successful but the data is flashing all over place. Ignition voltage rmp etc basically everything flashing and even the ECM software version and engine type is not recording properly ? Any suggestions i am using MEFIBURN with scanerpro (some reason tunerproRT is not scanning e...

pbusanga

If it was me, I would just power the fuel pump using the prime port or jumper in the relay socket, much easier than plugging in a computer to do such a simple task. yes! good suggestion ! just thought there was simple way to activate from poot as i would have it plugged in anyway for diagnostic pur...

pbusanga

yes is referring to commercial scan tool, just thought Tunerpro may have function to or way to operate fuel pumps etc. I bought the MEFIBURN scan program thinking it would do all that the scan tools do and more (not talking about tuning chips of course) but seems there are some limitations i was not...

pbusanga

anybody ?

pbusanga

does this only work when connected to the engine. Am looking at my list now and double clicking does nothing (while i am not connected to engine)

pbusanga

How do you run fuel pumps with TP, my EFI diagnostic manual for MEFI4 says to use scan tool to run fuel pumps for a leakdown test. Dont know how to get TP to run pumps ??

pbusanga

if i want to clear DTC codes in tunerpro RT for MEFI4.adx how do i do this

pbusanga

ok thanks guys (yes it is for the MEFI4 boat). guess i will just have to do the usual mechanical leak down tests and ohm tests

pbusanga

anybody ?

pbusanga

How / can i check if injectors are working correctly using tunerpro what do i look for ??

pbusanga

one way to estimate fuel usage would be to take the GPH reading, average it(can be done with the histograms, then multiply it by the amount of time the engine has been running(done in hours to make the conversion easy). avg 5 GPH over a 2 hour period = 10 gallons used it's obviously not automatic, ...

pbusanga

Thanks again ! Am beginning to get my head around this stuff. Cant imagine what it is like to get into actual tuning of engine..scary stuff ! I don't actually want to tune my boat engine just want to be able to monitor all its vitals and hope i can preempt any probs before i get stuck out at sea :) ...

pbusanga

ok thanks...hmm could be something to look into..considering we have fuel flow rates and engine hours and rpms all captured there should be some way to accumulate gallons used over time... HI Mark maybe something that can be incorporated into your software ... :) Could history tables be used in anyw...

pbusanga

Got it..thanks Charles.

the GPH item on mefi4 is an instantaneous gallon consumption figure. How would i convert that into actual gallons used from a given time.

ie when i start engine how could i accumulate gallons used ?

pbusanga

Thanks Charles...quick question when you link new item cant you watch it on the dash along side the original item to check is same, then apply formula ??? same as you would with copying the native one and renaming it. like i say i am new to this and my engine is not running so i cant test these for ...

pbusanga

oh ok i will look, i must have missed the GPH built in..too many late nights staring at screen

)

yes am using the MEFI burn and tunerpro software.

could you explain to me the principle of linking to rpm..how would this work what is the relationship to GPH

pbusanga

is there anyway to calculate GPH (gallons per hour) in real time and calculate total gallons used as a cumulative figure, in total and per trip. Would like to be able to use this software (i know is not intended for this) to calculate how many gallons i have used on my boat while underway. bear in m...

pbusanga

not sure how i would find out what voltage corresponds to what pressure ? i was hoping there was some kind of standard for MEFI4.adx oil pressure conversion. i created a new parameter (OIL PRESSURE PSI) and linked it to the original oil / CAT and then applied formula. Would it be better to use OIL P...

i want to link a new parameter called OIL PRESSURE to the existing oil pressure / cat parameter in my mefi4.adx, which is in volts. i have created the parameter and linked it to oil pressure/CAT, what formula should i use to convert volts to psi.
