Big update time!
I’ve been told to get this finished soon by Mrs W.
As the office, “is a f**king state”.
Completed the map line take off and the brake vac take off.
Also finished the TPS mount
More thinking.
Hole in the middle at the bottom is for the idle control air.
Tried loads of different ideas to plumb it to an idle valve. All of them required too much hose and fittings.
MG rover to the rescue. K series idle valve bolts straight up with a little 3d printed spacer.
Fuel system this weekend:
Made a little holder for the fuel filter so it can live at the back rather than the engine bay.
Fuel reg, sensor and fittings plumbed in.
ITB’s fitted and the engine side of the loom is done. Also done some random plumbing etc etc.
I hate wiring!!!!!!!
Also got the throttle linkage done. I had to go out and buy a new slightly thinner cable though to work with the bell crank.
When first set up I couldn't get full throttle, I’ve lengthened the pedal throw now, so should be grand, and a bit like a TVR to drive, as they have really long throttle pedals.
Rails in, injectors wired up, we have pressure too!
Ecu is
in the car too.
Also made a little bracket for the manifold air temp. Need to make it a little more rigid.
The ECU is alive!
Now set the crank and cam sensors in the fancy distributor
Well these HT’s are as tight as they could be!
Since there’s sensor inputs may as well used them.
Fuel pressure
Oil Pressure
Nothing is fun on a Sunday like taking an angle grinder to your bonnet.
Todays job - Mapping.
Never done an Alpha N tune before.
Far left screen - Terminators self generated VE map.
Centre screen - Old map from the Holley Sniper
Far right screen - New map using Alpha N
What’s impressive was how close the Terminatirs self generated maps was to my old one.
Now the fun of working out where all my fuel flows should go on an Alpha N map.
Things like idle and cruise will all be in the bottom rows, then it’s a case of filling in the WOT fuel and joining the dots.
The last photo is the old Sniper map flipped back to VE so you can see where idle and cruise was affecting the map.
So the little idle block needs transposing to the 1-2% TPS line on the Alpha N map and the lean cruise area needs to side in the 3-9% throttle area of the new map.
Since this all hurt my brain after a while, I had a break and did an alignment with my DIY string kit
All in spec, which is impressive since I eyeballed the re fitting of the rear end.
Oh you are beautiful. So happy with it.
Its all up and running now, tuning though came to an abrupt end, when I'd forgotten to put any fuel in it....
