Few Q's getting started

Hey everyone,

just wondering if there is a way to read error codes with tunerpro RT ?

Thanks

[VL400]

Yep, start logging and select the 'Data List View'.

Yet another question guys,

In the dash on tunerpro the road speed doesnt work yet my speedo in my car dash works, so shouldnt it work in tunerpro seeing as it runs through the ECM or am i wrong ?

Thanks,

presuming its a vn it goes from gearbox to dash and then the dash feeds the ecu the speedo pulses maybe you have an issue between the dash and ecu do you get any VSS error codes when driving .the vss code sometimes only comes up when you drive hard we dont even run a speed sensor and hardly ever get the check engine light pop up

The road speed gauge works, however it shows a lot lower than the actual speed. I think I read somewhere that the number of pulses in a vn is 5 times lower or something? Can anyone confirm if this is correct, and what we need to do in tunerpro to get this reading right. Its not real important, but would be useful when looking back at logs

[delcowizzid]

the PPK pulses per km setting in the top window of tunerpro will still be set at vr setting set it to 1250 i think vn is meant to be

[monaro308]

Yep its 1250.05 ppk.
I'm running the VR 082ecu with just a VN speedo guage hidden under my console for my devide x 5 in the munro.

Hey guys, having a few problems burning to eprom. Finally got a burner and added a socket to a memcal. Have tried burning even standard 12P bins, but each time it just goes into limp mode. Can put the standard eprom into the socket and it works fine. Just hoping there might be something simple I might be missing.

Cheers

What EPROM are you using? 12P requires a minimum of a 32k EPROM. There is a memory offset table in the getting started guide if your using a 64k EPROM.

VL400 is referring to the table near the bottom of this page https://pcmhacking.net/forums/view ... able#p7676

Being new to this myself I have a dumb dumb way of working it out. I read the eprom/ nvram i intend writing to so you can clearly see it's size in the read/ write buffer. Then i open the bin to be written as many times as it will fit into that buffer scrolling down and taking note of where the last loaded bin ends and where the next all FF or OO section starts. This is then where the next section starts.

Keeping in mind that the eprom will fit either 1 copy of the bin perfectly or if the eprom is larger than the bin being used it could fit twice or 4 times etc etc. Main thing is to have the multiple copies of the bin (if this is the what's needed to make the eprom full) finish at both the middle of it's available space (half way from top to bottom of the read/ write buffer) and also another exact copy of the bin (or alternate bin if you are using a bank switch set up) at the end of the eprom being written to available space.

Hope the pros will pull up any mistakes there but that's how I got my head around it.
