VCM2 clone review: SP177-C1 the best! seem to be the place to buy a decent clone their boards seem to be the good quality ones described on mhhauto,


I do use China clone with Mazda IDS and never had issue on 2010+ vehicle. Clone # sp177C-1 is working good also on 2010+ but this model isn’t available anymore.

As for sp177c , I have no experience with it. just make sure you don’t buy anything that’s based on allscanner/VXdiag technology. Those are complete crap


But don’t expect any clone VCM2 will do old PCM programming, because of the EEprom programming signal higher voltage required can’t be produced by those clones.

In short, when programming these PCM, the VCM sends a higher voltage (around 18v) to 1 pin of the PCM to “open” the programming session. Clones can’t do that.

the only tool that I know that does it is the new thing from FLY but….(and there’s a BIG but)… it won’t let you program some older cluster and ABS ecu. Ive tested it on some cars and so far, not so good.

Better get an OEM VCM2 as I did.
Buy 1 good tool instead of 2 or 3 crap tool




Never worked



1 – USB cable that came with it doesn’t even fit the tool. It’s just too big to reach the connector.
2 – they state same as sp177-c or sp177-c1 which is a big lie. Components quality is nothing near similar.
3 – most important.. it’s unusable. It keeps disconnecting from the laptop every 10 to 20 sec while watching data logger. I don’t want to even risk programming with it.



SP177-C1 is the best, then SP177 I think

A good price. Well worth the money.
