It depends on your car, and more importantly the engine set up, and ECU map.

Ahh, usable, makes sense now!!

Crikey, translation into English achieved (just).

Malcolm, the Emerald ECU has the ability to store several maps and these would be switchable. There maybe other ECUs which can do something similar.

so we could have a three position dashboard switch for road, track, town?

that's a very persuasive distinguishing feature as between ECU choices.

Or for road, track, MOT

MegaSquirt but it only supports two maps.

[anthonym]

that will be MOT and track for you then 😬

[gundersen]

Indeed

For that Fast & The Furious moment, have your laptop plugged in your ECU and at every traffic light Grand Prix, whip it out and press a few buttons to download The Sub 10 s Standing 1/4 Mile map 😬.

Only the later Emerald's K3 & K6 are switchable, between their 3 stored maps, however Dave Walker makes such a good job of the mapping that for most people 1 will suffice without any short comings at all.

I use my "touring" map almost all of the time which is almost identical to the "track" map but has a lower Rev limit. Also nice to have one map that has the change up light set very low. I use this when warming the oil.

I think that unless you have a very heavily tuned car then a second map for road use isn't worthwhile. In any case by the time you got there I doubt that changing the map alone would make that much difference over a car with a decent map to start with. It's not going to turn into a 1300 Fiesta, whatever you do. (Fortunately).

 

Having a lower change light simply for oil warming strikes me as a lot of work for not much benefit. A clever gadget, for sure, especially if you hooked it to a temp sensor so that it sorted it out for itself, but a gadget nonetheless. After all, a lower rev limit for cold oil isn't an absolute, it just means that you drive around like my Mum for the first few miles. The odd spell at 5000 rpm while overtaking is neither here nor there, even with cold oil, let's be honest.

I am not using an Emerald but unit from van Kronenburg (KMS), convenient as only an hours drive for me. They are normally tuning BMW M3's, Audi v6's and the like. They installed their system on my 1600 K and set it up on their RR along with an exhaust analyser. They believe the engine is set up correctly and needs only one map, the higher rpm for on the track is also possible but I can change that in a few minutes if needed.

MOT equivalent here is not an issue with their set up for emmissions at idle and 2000 rpm. Starts first time, fuel consumption good, and so is torque as well as 180 bhp. Dave's head along with the throttle bodies, 4,2,1 exhaust and cold air intake do help.

Boss,

It's not a lot of work at all. Just fit the switch and plug the laptop in. On one map I have the Change Light set low but not the rev limiter so I can overtake/get out of trouble if I need to. Another map I have the Light and Limiter set a little below max to avoid the temptation to rag the engine all the time. Agreed it's not a massive benefit but the ECU is fitted anyway so why not use the features for the sake of a switch?

If it's as simple as that then as you say it's a "why not" modification. If you use it, then it's a winner.
