Emerald ecu
I've had a great day today, got my car running...s2000, emerald Ecu. The ecu came loaded with a base map, I had lots of backfiring on initial
startup. After some tinkering with fueling/ignition etc, I managed to get the engine ticking over and running ok ish. I'm assuming that a
rolling road session is required for fine tuning? How well should they run prior to this?

If you have a wideband lambda system you can feed the 0-5v linear output into the emerald and either run it closed loop or put in a desired lambda map
and after running for a bit will tell you what to change the injection to in order to meet it. Either of these will get you close but to squeeze the
last few hp/lbft out ofnthe engine a roling Road session will be needed.

When I installed my Emerald ECU onto my rebuilt and modified engine I managed to get it running well enough to drive the car while my brother sat in
the passengers seat operating the laptop . I don't know if the later ECU s still have the ability to show a bullseye target for the load and
speed sites along with a bar graph showing the mixture but on mine it does . I drove at steady load and speed whilst my brother adjusted as required ,
did every other site then inter polluted ( if that's the right term) to set the unset sites Got it good enough to safely get a few miles on the
new engine before getting it onto the RR . Dave at Emerald told me the sites I had set were pretty good . If your intending on taking the car to
Emerald get it booked in ASAP

Unfortunately I do not have a lambda installed!

Out the box setting will be safe, rich and retarded so good enough to get to the rolling road, suggest you bite the bullet and see John at Emerald to
set up.
First thing, get a strobe and make sure with 0 advance its on TDC

So is the base map generic enough to work on any engine? I'm working towards a EFi conversion of my bike engine. I was planning on strobing a
timing wheel on the crank to work out the stock ECU timing 2D map and putting that into an Emerald ECU but if the stock map is good enough I
won't bother. I'll just drive it to them for a proper rolling road session

A usable base map (i.e. good enough to get the engine running) will be specific to the engine displacement, injector flow rate etc. There is no such
thing as a map that will allow any engine to run.

Agree with MikeRJ, the best bet is to call Emerald, let them know the engine and spec and there is a goo likelihood they have mapped something pretty
similar and so can email you a base map to work from. This will get you to the mapping session or can be optimised on the road with the help of a wide
band lambda system.

Emerald supply a dedicated map for the engine.
I have found a problem....cam gear that runs both cams has Sheared its bolt, luckily I found out at this stage and not 9000rpm!
