Inaccurate Tacho & Fuel Gauge

Post by fahad1417 »

Hi all, I purchased prosport evo gauges for my dash. I have had them all fitted with the help of MRTWOS, but we cant get the Tacho gauge to read anywhere near accurately. I even purchased an msd tach adapter, still no luck. It reads over 9000 rpm at idle, the fuel gauge is also not reading accurately. The guys at RSPEC who I purchased the gauges from are useless, no help at all. I paid alot of money for these and really dissapointed that I cant get it to work. Any help anyone? I dont know how to post pics or I'd show here.

i'm sure there's a resistor needs wired in. Hopefully somebody more clued up than me can help but I do vaguely remember reading about it.

Point us towards online copies of the install manuals and I'll have a read.

It would also help to know how you've wired them in so far, and whether you're using them as well as or instead of the stock cluster.
