| Re: Gurston Down Speed Hill Climb A Quick Update -
Rodger has been out running in his new 400+ci motor - running well I believe so he should be quick. (g-box permitting [img]/ubbthreads/images/graemlins/grin.gif[/img])
...and tonight saw Dave & I venture out in the R42 for some mapping, aided by the Motec Pro Lambda meter which was hooked to his M48 Pro ECU to give a Wideband Quick Lambda function from a preset map of target values. This was also the first test of the new BIG injectors that are being used on both Dave's 42 and Roys 40 (when I get round to fitting them) so an interesting time was expected.
We started by warming everything up and confirming that the actual timing was matching the required timing determined by the ECU. Then, after getting a reasonable idle, we ventured out for a couple of laps of his industrial estate at a lowly 3000rpm max. Another quick check of all under the rear deck and then off onto a nearby section of A-road / dual carriageway for some tweeking at higher rpm and increasing load.
This we did, confirming the rpm limiter at first 5000rpm, then 6000rpm. As Dave drove steadily I tweeked the base fuel map and we got some good pulls on a long uphill section. Alas, my laptop's battery did'nt last the pace and we returned to base after some 30 mins, but with a somewhat livlier R42.
One interesting point was that as soon as we pulled onto the A road, a Black '03' RSR Porsche blasted past and pulled in front, slowing to match us. He then proceeded to 'put his boot down' each time we approached - what is it with 'some' Porsche drivers???
Anyway, next session will see the 7000+rpm barrier broken then off to Gurston Sunday... [img]/ubbthreads/images/graemlins/grin.gif[/img]
Now, if only I could remotely adjust his rev limit....(he he he) - only joking Dave. [img]/ubbthreads/images/graemlins/smirk.gif[/img] |
