Emerald Mapping

Looking for somebody in the Aberdeen area that can doa full mapping with an Emerald on my Elise?

I think that Dastek should be able to do it (is that wallace performance?).

Having said that, I know that Tut/Craig had a variable experience with one of the rolling road places - might be worth checking with them.

If your car is a standard B&C 160 there isn't that much point in mapping it, though, as it won't produce much more power .... if you haven't done so already, I would do a power run with a well calibrated wide band lambda probe up the exhaust pipe and see what the exhaust looks like .... if it's basically 1.0 at idle, a little rich in the mid range and quite rich at the top end, you aren't going to release much/any power by fitting an emerald.

Of course if you've just fitted DTHTBs and wild cams, clearly mapping will be required to make it work at all

I might also be tempted to fit an LC1 wideband lambda sensor yourself (it has a narrowband emulation output, so will work with your existing ECU) - then you can log fuelling on a power run up the motorway instead and save the cost of the rolling road

Cheers,
Robin

P.S. A complete setup of an emerald is more work than just mapping it; so don't waste your money on the rolling road until you have set it up in the first place - otherwise you'll end up back at the rolling road when you make changes to the configuration that "upsets" your map.

This not true if you drive down to Emerald in Norfolk - Dave can set them up in his sleep, but it's a long way

Cheers,
Robin

Find someone who knows the emerald and take it to them its the quailty of the mapping that makes all the differance not the ecu imo
i would even hire a trailor if ness
dont forget mapping is about ingiton as well as fueling and that can only be done on a rolling road .get it wrong and your pistons wont last
dont bother being pikey with a share map as unless you know what comp ratio he has ( skimed head ect) its usless and dangerous plus if its a custom map it will bring all the other mods you have together
for what it costs fit a bario the sensor is only cheap ( punto)
theres a section on hubspace worth looking at regarding the emerald settings as a few have melted pistons due to coolent temp failure

obviously if the timing is out as much as that it will wreck the pistons. i dont understand why it was run until it got to that stage. it must have been pinking and knocking for ages before that, im sure the engine temp would have been a lot higher than normal too.

whilst i agree that in experienced tuners running shared maps is dangerous, if you understand what youre doing it can save you a great deal of time. obviously you wouldnt thrash the map before you get it rolling roaded and fine tuned, but it would deffinately be drivable.

most ecus are the same. more fuel less fuel, more ign less ign. the software looks different and i think the load tables are arse for tit compared to the Wolf3Ds that i run. but any 'tuner' will get his head round it in about 10 mins.

Both of my first S1's were upgraded to 180hp before I went the Honda route, but I found that by using a Dave Walker map from my large collection that was the same spec as mine, it was virtually spot on.

I went down to Dave's once with my map in and had a full mapping session on his R/R, and there was 1hp difference at the end of it. Ricky Gauld had previously modified the map to smooth it out, but the top end was the same.

There are so many maps that Dave has done that you can pick one for any spec that you could think up. My suggestion would be to let us know the exact spec of your car so that we could give you a suitable map, then maybe go to Wallace Performance in Aberdeen, or to Ricky, and get a power run done. Then look at whether it is worthwhile doing further mapping on a R/R with the associated expenditure.

Thanks for all your comments. Was wondering if Ricky had done work with these before Tut, top bloke, knows his sh!t. The question was for and engine that I am build at the moment. Be a bells and whistles K series, but was curios to see if it would make any difference to the B & C engine as it seems to run quite rich. Might try it any way with a 52mm throttle body and hurricane added, see if it will give 160bhp instead of 144.
