TVR Diagnostic Software Questions
Discussion
Good evening all,
Today I finally took the time to connect my old laptop (Vista) to the Tuscan, for some time there was an EFI fault and this time I wanted to kill it myself. After downloading the TVR Diagnostic Software, installing the drivers for the USB-converter, changing the COM-port and changing some file name, I finally got the software up and running
.
The only thing I didn't get correct was switching between the screens. The manual says the Page-up and Page-down keys are the correct controls, but whatever I tried (running compatible mode XP, 95,98) it stil wouldn't let me click through the screens. Found some old PH thread with the same problem, but without a solution
.
So then I tried EvoOlli's software and it worked immediately, so seeing there where no faults and the data looked correct, I erased my EFI fault. The data showing on the screen looked pretty good to me, but I'm no expert.
So a few questions I would like to ask:
1. Does anyone have a solution for my Page-up and Page-down problem in the original TVR Diagnostic Software.
2. Are there any differences in data or possibility's comparing the TVR Diagnostic Software and EvoOlli's software?
3. Looking at the pictures of the data, what's your opinion?
Looking forward to your response!

The original software wasn't the best, most annoying thing for me are the occasional dropouts.
But to answer your questions:
1. I never managed to get the original TVR software to fully work on any OS other than XP, so I'd suggest this is a compatability issue.
2. EvoOlli's software is very good and from my use, the data is identical, plus no connection issues, plus it works on all MS OS's. I tend to use it most of the time now.
3. Looking at the pictures of the data your car looks pretty healthy. The only thing you could possibly do is to check throttle balance as the adaptive's are not quite the same at idle. Having said that, they are close and if I went to check mine I bet they'd be different too! So nothing to worry about.

The lambda values should switch up and down between 0.1v and around 0.8v on a hot engine idling. Do they do this as a screen snapshot only shows the value at that time?
If the lambdas don't seem to move, give the pedal a flooring and lift off. The values should rise (towards 0.8v) as you inject more fuel (enrich) then as the revs drop down it should go lean so the value should drop to 0.1v for a moment then recover and start switching again.
The adaptives and the injection time all reflect this so a lower injection time will mean a weaker mixture and a lower adaptive reading which your screenshots are showing.

I thought the lamba's act like you describe, but to be sure I will check the next time I have the car running with the software. Thanks for the feedback and further enlarging my knowledge on the software!If the lambdas don't seem to move, give the pedal a flooring and lift off.

Hi, Can anyone give me a link to EvoOlli's software
It's the link in the first post of this topic:EvoOlli's software
Have you got a copy of the manual that goes with the TVR software? Worth a read.
This is the text for expected Lambda operation:
LAMBDA 1 & LAMBDA 2
Lambda 1&2 show the signals from the lambda sensors on each set of three cylinders. Lambda1 is the front three cylinders (ie. cylinders 1,2&3) and lambda 2 is the rear three cylinders (ie. 4,5&6 ). After starting the sensors will take at least 30 seconds to warm up, before they will read correctly. Once warmed up, the lambda signals should switch between approx. 0 & 1-1.5 volts. 0 volts shows that the fuel mixture is lean, 1 volt shows that the mixture is rich. The rate of switching will alter with engine speed, and the percentage of time spent rich relative to lean will alter with engine load. If reading is a CONSTANT 0 V, check sensor for proper connection, and sensor heater wires for continuity (6 ohms between white red wires)
NOTE: Lambda sensors are supplied with 12V on the red wires ONLY WHEN THE FUEL PUMP IS RUNNING, the WHITE wire is earth and BLACK the signal.
