Emerald Map for VHPD Required

[jonhill]

I'm hoping to trial a firend's Emarald on my SLR tomorrow afternoon, so can someone email me an appropriate map by then?

 

My engine is a 2001 spec. VHPD, with the PTP DTH TBs (not the horrible swan neck Rover ones), and unmodified in any way.

 

Email to jon.hill7@virgin.net

 

TIA,

 

Jon

will having my map to you within the hour. Its either here at work or at home. Have several variations to try.

Andrew, thanks.

 

Any idea how close a match your maps are to those for a STD VHPD, given your ported head makes an extra 20-25 bhp? What tweaks would bring it closer to the ideal? Would it be risky to use high rpm with this map?

 

Cheers,

 

Jon

My SLR map was done on Dave's rollers a couple of weeks back. Totally std engine with the PTP bodies. Raceco silencer. Cam timing corrected to Piper's spec. 209bhp@7600 + 155lbft torque

 

Let me know if you want a copy of this map.

Hi Julian,

 

Yes please, can you mail it to the above address.

 

Any idea of the implications of running this map on my engine, given my std cam timing?

 

209 bhp! Blimey, you must be chuffed with that. Did you run it on the rollers with the MEMS first, for a comparison? How does it drive now, compared to the MEMS?

 

Thanks,

 

Jon

No Jon, didn't bother with MEMS beyond about 500 miles because the car was such a pig. Dave spent about 4 solid hours mapping for the power curve on display at :

The car is incomparable to standard (but remember my MEMS was so bad that the car wouldn't idle unattended for more than about 20 seconds, even when warm.) Now I have a steady, consistant idle, good - but not totally perfect - low speed manners and a massive wall of torque where before there was just lots of noise. The car thumps forwards in any gear and is so quick that it was all over the "300bhp" turbo 7 at Donnington on Wednesday......(I'm an "average" driver - but the engine is just very easy to get the best out of which is crucial if you're not Ayrton Senna)

 

It's just awesome, and whilst the power peak is 7600 (power still climbing), the real story is the power available out of the corners, which is "a lot" from 4500rpm upwards.

 

Get a set of verniers from Dave Andrews first though because the cam timing was pegged wrong by the factory wheels.
