any megasquirt boff's in the midlands
with stoneliegh only 2 DAYS AWAY!!! i am on the verge of going into dyer straights mode and im on the verge of pulling all my hair out as well,
i have been trying to set up my megasquirt for a day and a bit all day yesterday and three hours tonight and im still not got any firing or anything,
i have followed the advise from extra efi and i still cant seem to get anything happening.
i think that the main problem i have is that im not recieving a signal from the crank sensor, i posted last night with this problem and got several
reponses (thanks to those people) but when i tried there recommendations i still not getting a signal generated to the ecu.
is there anyone in the midlands that is any good with MS and wouldn't mind popping round for a cup of tea and a consultation. i live 2 miles
from stoneliegh so you could even take shelter from the rain on your way to the show
please help
I love Pinto's, even if i did get mine from P&O!

Megasquirt.....................
If its any consolation , Chris Cook took mine away tonight to see if he can work out why it wont work........
As for the crank sensor issue - are you using a VR or hall effect ? If a VR sensor , have you tried swapping the wires round , as it is possible to
connect them backwards and get a rubbish signal .

yes i tried swopping the wires over and it made no difference, the ecu didn't pick up the signal either!
i really dont know what t do next?

OK - so the first thing I would do is check that the sensor is working properly - I checked mine by passing a spanner close by it with a meter
connected to be sure the sensor was sending the correct signal ( just had a quick search on the megasquirt site but I cant find the information I used
)

yep did that, took the sensor and put it in the vice, i then passed a spanner and a metal file over and the needle moved on the meter.
i have two wires coming out of the sensor, a pale blue one,which i am assuming is the signal wire as the othe is black, i have connected the pale blue
wire to the +ve wire from the ecu and the black to the -ve side

Are you guys running edis or the on board VR sensor circuit?

Check out the reply in your other posting , you need to configure the board and software to work.

I`m confused - can you give a bit more info on your setup as I dont know a good reason to keep a distributer if using a megasquirt ?

im running 2.1 pinto with r1 throttle bodies. uses single coil and dizzy, i have water temp sensor, air temp, map sensor (built into the MS unit) and
trigger wheel,
ive kept dizzy for the time being and will upgrade later, running out of money, plus you get a better spark accuracy with a dizzy rather that using a
wasted spark system

Don't understand this statement, the dizzy is a clockwork 2D system the magasquirt + spark or Megajolt is a 3D system that you can accurately
set for any load and revs, thats the point, its more accurate than a dizzy

Gotta agree there - and from what I`ve read so far there is nothing straight forward about setting up a megasquirt to run a dizzy.......
Edis units can be had off ebay for very little , and coil-packs are cheap and plentyfull in the scrappy - with the added advantage that the engine
will run on just the edis (very handy for checking wiring ! )

I would guess that your board is designed for a standard hall effect input of 0-5 volts, but a vr sensor has an analouge signal which will only
produce voltages this high at high engine revs.
Put a vr signal amplifier in, that will condition a vr signal to digital.
Also what is the air gap it should be very small in order to get a strong clean signal.1 mm or less if i remember correctly.

The board incorporates a vr sensor input circuit , but it does have to be setup to suit the sensor.

r u saying that i should scrap the dizzy and install an edis instead, they are on ebay for £35 reconditioned

Yes - allthough with a Pinto you will then have to sort out an oil pump drive if you remove the dizzy......

Leave the distributor in place to drive the oil pump until you get the engine up and running, sort one problem out at a time ?

You could still leave the dizzy in place to drive the oil pump , or cut it down and seal over the top bearing.
It should work ok though if the crank sensor and trigger wheel are set up correctly, to go to edis would need some rewiring and reconfigering of the
ecu .
I would go to the megasquirt forums and find the set up pages for the ecu and go through the settings for Vr sensor and a single coil.

For speed, I would forget your trigger wheel setup for now as you seem to be getting confused. Use your dizzy and take your tach input signal (to
megasquirt) from the neg(-) side of your coil. You'll need to configure your MS board to accept either a points ignition signal or a VR signal,
depending on how your dizzy works.
from MS megamanual
52. Select the tach input circuit with jumpers:
For the VR sensor:
Jumper VRIN to TACHSELECT on the bottom side of the PCB (near the DB37, opposite the heat sink.)
Jumper TSEL to VROUT (Or VROUTINV if you want the VR input to be inverted) on the bottom side of the PCB, near the center.
OR (Do NOT install both sets of jumpers, chose one set or the other!)
For the Hall sensor, optical sensor, coil negative terminal or points:
Jumper XG1 to XG2 on the bottom side of the PCB, near the 40 pin socket,
Jumper OPTOIN to TACHSELECT on the bottom side of the PCB, near the DB37 connector, opposite the heat sink.
Jumper TSEL to OPTOOUT on the bottom side of the PCB, near the center.
When you've got this running get the trigger wheel setup sorted after stoneleigh. A crank sensor (trigger wheel setup) requires the MS board to
be configure differently. You also need to setup two pots on the board.
When yopu get round to the crank sensor setup, if your dizzy drives your oil pump, you can use the bottom half of the dizzy drive gear, i.e cut if
off, make it look pretty and refit without the top half etc. Use a roll pin to keep seals in situ.
Cheers
