Not much been happening on the coupe as late, but working on the 120Y in the garage
next to the coupe, I started to pine the coupe, and the promise is has to me of
singing sweet tunes on those ITB's......
And after a big disappointment after trying to fire it up at weekend for Mint16 & Kev
and it barely firing let alone idling or revving, I have spent a few hours on the net
researching Megasquirt configuration and tuning information, I found that I had
quite a few settings a bit incorrect, and have learnt quite a bit more in the process,
its all new to me, and quite a steep learning curve.
I am not looking to tune all the Fuel rates or A/R ratios at this point in time, nor start
up the on board ECU driven wasted spark coil ignition setup, I just want stable startup
& rough running, to know its ready for fine tuning and testing, when the car is back
together after painting - thats when all the real tedious fine tuning will happen.
So I started up last night, after adjusting quite a few setting, and still no good
Tonight I went back to basics, checked spark - which it had, then I pulled out plugs &
they were dripping wet with fuel & residue (from over fueling and the likes)
put
another old set of plugs in that I found, and away she went, something wrong with
my cranking settings as takes ages to fire, and takes a wee while holding starter
motor on blipping the throttle before the engine running really "takes", but once it
has, its away into smooth-ish idle (all be it at elevated rpm) and is quite responsive
in the revving, but it is still over-fueling, as backfires at higer revs, and puts rich
blackish smoke out the exhaust. I adjusted my dizzy to run about 8° advance at
(elevated) idle speed. I might get brave at the weekend and test my new ignition.
Anyways - she is starting to make the right noises, a more successful vid here:
