rinda scan tool rpm check/test issue,

[ADRIAN B]

hey guys pluged in my rinda scan tool to my 5.7 mpi serial 0w001983

so went into do a fault scan that was all sweet no issues so far,

then went on the test the tacho, it sayd it will do a test to 3000rpm so test started and gauge on dash goes to 4000rpm so it looks to be 1000rpm out is this going to cause issues, ??

thanks so much first time poster very long time reader hoping dons will pop in with his wizard skills hehehe.

Re: rinda scan tool rpm check/test issue,

Well, it's telling you your tach is wrong. The issues you will have problems with is if you try to prop it with incorrect readings. Your tach says you are ok, and you are actually lugging the engine, or over revving it, depending on which what it's off. Neither over or under is a good thing.

Re: rinda scan tool rpm check/test issue,

so its only the tach gauge that is wrong,? so if i plug in the rinda and start the engine the rpm on the scan tool should be different to the gauge on the dash by 1000rpm?

could this be a ground issue?

How does the scan tool rpm compare to the tach at the helm, with the engine running?
