As i sad you can keep one relay to switch 12v to the fuel pump and injectors but of course you can use 2 relays one for each other the idea is to switch both on with the FUEL PUMP WIRE form the MS ECU witch is a ground ( 0v ) switched by the ecu. The stock injectors are good for about 1 bar of boost...

The fuel pump wire that goes from MS is actually a ground that switches a relay on/off,relay that powers on the fuel pump.
It is advised to power on the injectors from the same relay as the fuel pump.

P.S. I have now switched from MS2 Extra to MS1 Extra with experimental ALS.

PM pending,regarding Megasquirt

Yes it works.A friend of mine is now going Coil on plugs,and the pickup signal is the same,the stok one

OK,so how do you count the teethes ?
Please save and edit the picture !

P.S. If the engine is turning counter-clockwise,than the logic is that before the next top dead center there are 4x teethes to go !

So the problem is as follows : I've started long ago from gixfighter's msq,there was 258 degrees as Tooth angle,build the maps from there,car goes like rocket. Yesterday looked at my second engine that lies around,found out it's actually 90 degrees and today I've managed to re-build my maps but the ...

Wheel that chart is wrong way around,found the answer from the user who extracted this map ! Hey Thanks for the excel tip - graphed all my tables now (fuel + ve) for the F7P - looks amazing Smile Looking at the above graph for the B18FT i've just noticed the load scale is the wrong way round, which ...

What's you trigger offset at TDC in MS for the 60-2 flywheel ?

any opinions on that advance map ?
I'm not sure the RPM / Load are the wight way round !

Although my engine is ruining fine,the ignition map still buggers me and i think I'm not getting the best out of this engine that way ! Common sense is with boost increase back the advance but what i've found and posted already is somehow wrong ! So can anyone of you post they're ign map to debate a...

I am running this map now with no obvious detonations...i mean i can't feel anything spooky in the acceleration,and can't see no spikes in the rpm line,but i have troubles tuning the KnockSenseMS as i think i have a lot of noise under the bonnet,and the sensor picks false triggers ! AFR is no leaner...

Yeah,I've noticed that i am pushing the 100% duty cycle at 12.5 AFR,and sometime 110% while spike occurs after changing gears,so i also moved on to ~300cc Now,i have a Q for GixFigher : Are you shure your advance table from your msq posted some pages ago,is the stock one ? I am asking because i have...

As yknot says !
If you live in UK talk to Philip at www.extraefi.co.uk he will sort you out.
After you have that,come back and ask here !

Finlay car is running full boost on MS2 Extra !
1 Bar @ 11.5/12 AFR,stock injector Duty almost 100% so that's it for now on the stock engine configuration !

GixFighter can u post a datalog with idle after warm up enrichment and if u can also with a acceleration under load (on the street)
I can't bring my idle down from 1300rpm and is becoming really annoying as i can't figure out what's wrong !

Installation is easy,I've used the original loom to wire the MS to the engine.And u do not need to cut it off,so you can use it with the original ecu in case MS fails !

If u buy the MS from DIYAutotune make sure you buy the already made wiring,do not bother to make it yourself !

solved,thanx.
now to tuning

After some time on the shelf I've put the MS back on the car,removed the R57,changed the VB921 ti the better BIP323 managed to start the car but i am stuck on something stupid : TPS Signal got no feedback ! MS states is fully open (112%) and i read 4.6V on the wire.Moving the Throttle does nutting t...

i also noticed that if my battery is low on voltage it wont supply the ecu enough current to start the injectors ! When i was cranking the engine i had around 7V in the system and the car wont start (the pump did not go on and the injectors got no 12v) I put the battery on a 220 recharger and after ...
