so i started digging because cheap data logging is entertaining to me.

per defi's counterfeit pages, the connectors will be different, meaning that 'genuine', or 'known-great-quality' sensors/gauges are not going to work. so one would be committed to the cheap stuff for everything, or hacking connectors..

this review from 2018 also shows how the gauges are all 'close', but all off by some margin, and would require independent calibration to get accurate readings

also important is that defi discontinued that model in 2021. the newest model retails with sensors(turbo, pressure, temp, obd2) for $2715 at tein, the US distributor

evasive has it for $2444

so the question is, is the lack of accuracy, product quality, support, and being committed to questionable sensors worth a $2200 reduction in price?

honestly, i think for the roughly $200, one gets a lot of features. for a street vehicle, i'd be willing to play with it and would consider it a valuable addition(but non-critical) for engine monitoring.

but for anyone that demands reliability, accuracy, quality sensors, and any amount of product support, i lean more towards the genuine product, even at it's high price point.

i mean, 1-2 degrees off in temperature isn't terrible, and even being 0.4v off on voltage isn't terrible either. one could learn to adjust their mindset based on the gauges inaccuracy. but the fact that their inaccurate at a single reference voltage doesn't lend a lot of credibility to them being equally accurate across their entire sweep, which is really where inaccuracy plays the biggest part.

it's easy to adjust for +/- 2 over the entire sweep, but if it's -10 at the low end, and +10 at the high end...
