I used to use NGK AFR (NGK Performance Products - Powerdex AFX�) excellent bit of kit. This is was integrated into the map on my Emerald K6 ECU.
Excellent reviews and extremely accurate. Jim @ JKM Performance mapped my car with it.
how much was it?
Sorry to hi-jack slightly Darren
These use feed from cars lambda yeah?
Has anyone tried any of these gauge apps on android or iPhone?
Do they give similar accuracy?
I am using Innovate motorsports one. I used on my other car too and both had no problem till now. Also imo fits good with the dash lights color.
Innovate Motorsports DB Red LC1 Wideband Air Fuel Complete Kit 3796 | eBay
i use a techedge 2j2 imo the best you can buy around £300
i have wired it into my emerald k6 , for closed loop/adaptive mapping ,
Im still undecided on this one. Not sure if a like the digital read outs, think I prefer the needle sweep style - Yes, you can call me old and unfashionable!
best you can buy for what reasons?
Its double the cost of an AEM for example...
it can do data logging (if you want) and is very accurate compared with the bosh industry standard lambada kit we use a work and its reliable
Aem is all so a very good bit of kit as ive seen many of people using it
it all depends what you are using it for
