Car Ready For Tune, Cluster Stopped Working!?

[Rivet33]

My cars in for tune in the next week or so, and I've now noticed my cluster has decided to shit itself

Will this mean the car cannot be tuned as he will have no comparison of revs , speed ect, or can he tell via his computer ?

Any help would be appreciated, just don't really want to spend more than I already have this month as i drive the car once a month if that? And if it can be done at a later date would suit me better

Cheers guys

can tell by ECU

I don't think it would matter, but doesn't the ecu get the does signal from the cluster? Either way the tube will happen no worries

Speed signal at the ECU definitely comes via the cluster, so if the cluster is dead, no speed signal at the ECU. Depending on the ECU, this may or may not be a problem. If Nistuned standard ECU, then attempting to tune without a speed signal could be problematic. A lot of the Nissan ECUs go into various panic modes if the load gets high with no speed signal.

I know for a fact my old RB20DET ECU when I snipped the pin for the speed input on the ECU nothing happened & I could go over 180km/h

I'm pretty sure nistune gives the iron to switch off those type of cuts

[GTSBoy]

True, although again it appears to depend on which ECU you're talking about. They're not all the same same in these details.

Thanks guys, rb25 s2 running a z32 nistune board, anyone had this before?

Heaps of help guys, legends!

Z32 is same basic ECU as the R32 GTSt and GTR ECUs, so it should behave itself with no speed signal.

i remember when one of trent's customers broke a speedo drive mid tune, had to stop tunning change the speedo cable to start tuning on a rb20
