Have had TorguePro a few weeks and doing most testing on the Viggen but it communicates with all my cars. Started with a cheap ELM 327 Chinese unit bought off ebay but switched to the Kiwi and got much better results.
Issues:
Enjoying the app but finding it takes a bit of calibration tweaking in the settings to get accurate readouts of many parameters, particularly turbo boost and MPG.
The MPG calibration number is very sensitive. I had to go to three decimal place (I.E. 0.983) in the setting to get the numbers to come close to the numbers displayed on the cars info display. A setting of 1 or -1 would over/under read reported average MPG by as much as 30%.
I find the HP and Torque numbers to be largely useless. Both way under read when compared to dyno numbers. The Viggen can generate 270HP & 317 ft lbs on the dyno but highest readings I’ve seen from TorquePro have been 180 & 240.
