Hopefully we won't have to wait long to find out

Unfortunately we have been let down by the guy fitting the Microsquirt, the car has been with him for a while now so we have made zero progress but now that we have the car back we are fired up and raring to go.

The good news is that now the car is back we can crack on with the following:

-Weight reduction, Hardtop glass, door glass, door carcass, bin the stock heater, throw carpets in the bin, scrap the dash and binnacle, trim the loom back to the bare minimum, put the bonnet and boot lid on pins, throw the boot tub in the bin, fit a new aluminium tank along with a swirl pot and pumps.

- Roll cage fitting, weld the feet in fit the cage, ties in with the fuel tank piece.

- Fit the new Tillet FIA seat, maybe change the driving position slightly to assist with the offset pedals and fit the new FIA harness.

-Aero, look at doing something with the nose cone, add a spliter, remove intercooler scoop and move intercooler to the usual position infront of the radiator, possibly a flat floor and a diffuser although all of this list will depend on the amount of time we have left pre-season

- Increasing mechanical grip to make the most out of our existing tyres, not actually sure how yet but we will discuss shortly, we are still running the stock rear ARB at the moment so thats one possibility.

- Fit the new forged engine and BMW gearbox, have a new propshaft made and balanced to suit, then run the engine in.

- Fit ECU and have it mapped, originally when we bought the Microsquirt we were more concerned around budget and just making the extra power, our view has changed on this now and we are more interested in getting the best ECU possible to allow us to leverage extra features in future like antilag, launch control, traction control, multi map, boost by gear etc, Paul has kindly offered to wire up and fit the ecu and has suggested an Emerald but dad was concerned that the Emerald unit albeit good was getting on for 10 years old, dad was thinking of going Megasquirt and fitting ourselves but having spoken to a few local specialist most notably TDI north they prefer Link G4+ ECU's so we are looking into that, we have also yet to get hold of EFI-parts just up the road from us who come highly regarded but are proving difficult to communicate with which is not a good sign.

I have one in the Coupe.. very nice but not too easy to configure to your sensors. Having said that you could use canbus for most of it?

Well I found this relating to the Link ECU https://www.race-technology.com/wiki/in ... V74uvxrUfM

Once we have decided what direction we are going in I will give you a shout, it will definitely speed things up having you on-board and I really do not want to miss the start of the season.

Emerald is updated regularly, M3DK was 12 years ago, K3 approx 8yrs ago, K6 3years ago and K6+ is sort of unoffically available now :-)

Most of the other ecus are based on 5yr old+ tech, but managing fuel and sparks hasn’t changed, so it's only added features that requires updates, twin fans switching alternately, leccy water pumps, VTEC cam timing switching, adjustable boost and switchable maps on the fly etc. Most have traction control and launch these days, some are passive some active (big difference in tech debatable which suits speed events best), datalogging (useful to see what happened, but doesnt stop it happening of course), parameter alarms for low oil pressure, fuel pressure, engine temps, and engine shut down if goes past alarm stage-- can save an engine. Full throttle shift, gear cut, anti lag (again fuel based, fuel/air based or air only windmill ALS) all possible with most ecus, but its the application of the ALS which is the clever bit. EGT sensing, closed loop wideband lambda.

All nice to have, but often beyond the tuner on a dyno, needs real time and effort and more importantly, understanding, by the user to get all working independantly (labourious) and then get to work properly in harmony (needs a bit more nouse...).

I spent half a day at Curbs testing, and one of the Brit Hillclimb Top 12 single seaters was doing launch testing. Car never moved forwrd further than 30ft, connected to a laptop and coily lead, all altering the interactions of the fuel, spark and wheel speed---clever stuff, but beyond many.

Dyno tuners are everywhere, ones that actually know their onions, less so. Ones that can apply ecu settings to make the car quicker over a lap--rare indeed.

Getting the ecu mapped for power and engine safety is paramount, most can do this to be fair. Mapping out boost spikes can take hours after the pub figures are achieved. Settings for ignition retard, injector duty cycle vs throttle opening for launch, that’s tricky. Setting traction control isn't just picking a setting, as the grip levels alter as road speed increases, as tyre surface heats, and that’s without factoring in the rapidly altering torque as boost rises.

Love ecus, but its not a 'bolt on' part like spring or new seat, its only as good as the mapper and then how much effort you add to it :-)

As an example, on the Sabre i have reltively simple launch control. On my best day, i can better it, BUT its a constant, whereas humans arent. For a reliable get away, it works really well, but its not infallible or always beneficial.

I think there is risk the technology drives out the enjoyment in the pursuit of perfection. If you’ve got a well balanced, tuned car then the fun really is improving your own skills to maximise what you’ve got.

My first flatmate spent thousands on top notch hifi but all he could hear was the imperfections in the recordings, not the soul.

A mountain biking race colleague would have the cutting cutting edge stuff, costing >£10k pa, but I would beat him because I trained more, rode harder and I enjoyed riding.

But on another note, I think what you’ve done with the yellow one is fantastic.a brilliant example of how to try to make a step change, and mostly with your own skills and enthusiasm. )

The tech is another facet of buidling a race car imho, its no more complicated to the modern generation than balancing triple carbs and setting bob weights in a dizzy is to the old school types. Tech moves forward, GM engines in GTEs, modern quaife diffs etc, whatevr floats your boat 8)

I completely agree with all of that, my argument is TDI north are local and like link ECUs, they have produced some decent projects and this extreme ECU is only a few hundred dearer so we might as well. I'm not expecting to just bolt it in and raz off.
