Question Normal 25 1.4 103bhp torque chart?

I would like to compare my remapped ECU very well done by @lolsteve98 (SAWS Tuning) with the regular ECU of a standard 25 1.4 103bhp (in good order of course!) before / without remap.

Could a MG ZR 1.4 105 have a similar chart as a 25? In that case, a MG ZR chart before / without remap would be convenient as well.

Thanks to Torque Pro looking in my new remapped ECU, I assume that I shall be able to get out a chart.

Thanks to any of you able to post that "normal" torque chart.
And Happy new year 2017 to you all with my best wishes.

Eventually, Normal 25 1.4 84bhp torque chart will be helpful as well.
Nobody can get any graph with a good dyno?

I don't suppose many people have had reason to need the power/torque figures for a 25, but as the 25 (103ps) and the ZR (103ps) are mechanically identical apart from the suspension and wheels/tyres, it would be safe to say that the power/torque curve and specific torque figures will be the same for each engine.

There is likely to be a small difference in the figures for the engine as fitted in the complete car due to the slightly different diameter of the standard tyres fitted to each - the ZR tyres have an overall diameter around 3cm bigger than the standard tyres fitted to the 25.

Thanks @Man in the Car. So I'll turn my question in that way:

Normal MG ZR 103ps power/torque curve?

Are you honestly suggesting that the same engine will have a different power output depending upon the wheels that are fitted?

And, thereby, implying that if you take the engine out of a Rover 25 and put it in a ZR it will, somehow, gain more power.

Errrr, no - you are totally misunderstanding. The output figures will be the same for the standalone engine, but the relevant figures relating to performance in the complete car will be affected by any differences in the driveline, including wheel and tyre sizes between the 25 and ZR.

What I am suggesting is that the differing tyre diameter will be likely to make a small difference in the torque available at the wheels. However, it isn't really a suggestion - it is a simple matter of physics.

I have made the obvious conclusion from what you have written (as have others who have been in touch).

I would suggest that either you haven't explained yourself very clearly (I do hope you don't write for a living), or you don't fully understand things that well.
