The relay has a permanent 12v, and an ignition live/switched earth.
The ecu switches the earth to close the switch and send the 12v batt to the fuel pump wire.
So if it keeps dying it may be down to something like a dodgy crank sensor, meaning the ecu isn't reading the engine speed intermittently, so it thinks its not running.
Fuel pump should be fine, the same spec pump is whats used on 2L 16v's and Let's etc.....

should work as well but the inlet manifold will be the real killer as these tb's use the old sidedraft carb design. probably a lot cheaper I know but Warren seems to be having the usual hassles that people have with Megasquirt. comes down to hassle and power vs cost at the end of the day

Ive not seen the manifold the Dbilas kits use, by you mentioning side drafts i assume thats because the inlets you supply for jenveys etc are the angled type, so flow down and better into the ports.
Megasquirt can be complex to set up, but its a very capable system and works well, very well.

the inlets on the dbilas arent great, we have converted some dbilas tb's to our 30 degree inlets with great results.
megasquirt is good, until you use a properly designed engine management system.

Car rolling roaded at Torque of the Devil
power 129bhp @ 6500rpm
torque 101lbft
nice flat toque curve - a little low though
power isnt bad concidering only revs too 6500rpm, will be 8000rpm
and running standard management which it doesn't like at all
few pics - new standard number plates fitted (much better) and white bumper refitted
On the rollers
Graph
4 bar fuel pressure  hope the injectors can cope
Megasquirt running! (wont rev though, crank sensor signal dropping)
now with a x20xev coil pack, which fits on standard bracket
setting up ignition timing with strobe light
laptop display

Duid this start off as a 1.6 or have you done a conversion

top work warren. hows the new management goin?
can hear the engine screaming "please let me rev!"

Nice vid.
You can hear it pulling hard as f**k when it smashes into the limiter 
I wonder what it'd do on the standard ecu with a raised limit("superchip")
Think i remember you saying youve already got problems with the afm air reading being out of range though??

poor engine, its being strangled
going to get some 'resistive spark plug' or something :boogle: and some resisitors to put in the crank sensor wires, hopefuly will stableise the crank senor signal and wont keep cutting out

well when you put your foot down, at about 5krpm the light comes on, guess its out or tolarnces on the airflow, but cant check the codes as tech 1 wont communicate !
would be interesting to see what it would do though

Could have tried fitting the chip out of mine at the rr day see if it had worked

different ecu's gavin
still cant get the megasquirt to run properly
tried resistive spark plugs, moved earth to battery, put a resitor across the crank senor (then it wont start at all)
running out of ideas
wide band o2 senor on order for when is working, so can map it

But what are you going to do about the ignition map? Thats the tricky part.
If its not reading the crank sensor signal right then either the crank settings in the MS are wrong, or the crank sensor is too far away from the trigger teeth or something.

the crank sensor is fine - been running on the standard managemnt for ages now
igntion timming is set up (used a timming light) car start with in 2 seconds and idles fine
when you try and rev it, the crank signal drops to 0 for a split second, causing the no spark, then picks back up and drops off again
but reads fine when idling and ignition advance is set about 10 degrees
going to send phil a log to show him whats happening, and will see what he says
its crank signal/voltage related, but what i dont know

When mapping it how do you plan on holding the car at the paticular load site you are mapping at the precise rpm site you are mapping?
its very tricky without a dyno, by the time you get the rpm and load correct you will find that by the time you look down to adjust the map you will have gone past it.
same applies to the ignition timing.
How are you going to measure wether the cahnges you are making in the map increasing or decreasing power?
How are you detecting the required timing advance and the onset of knock?
(not having a go at your method, just curious and I may be able to advise and help )

well theres a program you can use to log all readings, so you can go for a drive, and see if in certain area's/loads are running rich and lean, then adjust the map
start by tuning the lower rpm, then move up the rev range at different loads
the igntion might be more tricky that fuel, like you said, working out how much advance you can get/ to optium power
but i plan to do the best i can on the road, then go to my old college and get it on the rollers there and see
if im not happy, then theres a place localish to me that ill finish my map for me

Is the cable shielding grounded? Maybe picking up interferrance.
Also check the bottom pully/crank sensor bracket isn't loose and letting the sensor move.
A good crank signal to the std ecu, the MS may not like.

has sheild wire all the way up it
phil has suguested i swap the crank senor wires over and give that a shot
so will try that tomorrow, if that doesnt work going to do a log andsend it too him so he can tell me whats wrong
no brackets fine, but will double check, but works fine on stanadard managemnet

Aye, swapping the wires round is a good call.
