[DML] EFI: Adaptronic ECU

Hi All,

With all this talk about EFI conversions and the issues I keep reading 
about by those using MS systems I'd like to share my experience of the 
Adaptronic e420c system.


It's an award-winning australian (available in the US) system which I 
selected for several important reasons

- cost

- sensor calibration

- ability to program just about any trigger pattern, including the daft 
Renault 66/3 signal. It does support odd-fire after I asked for it.

- ability to run batch fired injection and distributor - as with the 
original Renix ECUs on the Renault 2.5 turbo. The ECU has no concept of 
#1 cylinder. Most ECUs require this.

- the superb auto-tune setup when plugged into an Innovate LC-1 which 
gives it its name, this includes ignition tuning, but is not a magic bullet.

The above allow me to run an Adaptronic from a Renault flywheel within a 
later UN1 bellhousing. All native bolt-ons to the DeLorean engine.

Recent additions which have had me weak at the knees include tuning by 
VE and throttle-map prediction which was instigated to get around ever 
present throttle response issues. All ECUs have some sort of "throttle 
pump" parameter but these can be notorious to tune. The guys at 
adaptronic came up with a neat solution - you set up a very simple table 
of MAP values based on TPS, then whenever the trottle is moved, the ECU 
ignores the MAP signal for a predetermined time, say half a second. 
Here's a little video

The Adaptronic can very easily be hooked up to the stock ignition amp in 
the DeLorean.

The new 1280 ECUs are even more feature-packed than the now old e420c 
I'm used to.

Wiring is simple and I've not had any issues with simply connecting the 
grounds to the point behind the rear carpet board, and the switched 
supply to the feed for the RPM relay. Seperate supplies to those items 
being powered and controlled via the ECU include fuel pump, cooling 
fans, idle control, chargecooler pump and fan (and these are just the 
ones I've used!). I use the stock idlespeed thermistor as the primary 
engine temperature sensor - it has a very nice spread.

I basically feel a bit impotent with all you guys discussing MS. I would 
be much more use if some of you strayed from that fold and into mine ;-D
