Mapped or not?? with graph

Rnash2002 · Feb 25th, 2015, 21:24

Ok my question to the people in the know, is this a mapped ecu, the car was only running around 11 psi so to me its massively over fueling at peak power?
And that was whp also.

No idea whether after market mapped or not, but from the registration mark visible in the printout the DVLA website reports a 1998 Volvo with 2319cc engine - so either a very down on power T5 or a very badly calibrated rolling road.

Sorry its a v70 t5, i have changed the ecu for mine and on this one the throttle response is so much better than mine so made me think it was mapped, car was only running 11psi when it was on the rollers and its whp not crank.

Dyno Dynamics rollers often read low so I wouldn't read too much into the BHP figures. It could be standard and just need a bit of a service.

That's how Top Gear started the myth that cars loose power with age. (By measuring on mobile Dyno Dynamics rollers with no cooling)

Elastic tape-measure springs to mind.

Going to get it mapped anyway, was strange though as soon as i stuck this ecu into my car the throttle response was so much better than my standard (know it was standard lol) ecu, very strange.
