my cars up and running but im a bit confused with the injector banks

my ecu is a semie sinquentiol firing so it fires 2 injectors at a time ive got the left 2injectors as bank A and the right 2 injectors as bank B it idals but when revs it couthes and bangs can some one advise me please

 

pleaseeeeeeeeeeeeeeeee amy one

 

would help if you said what car / engine / ecu / injectors and what you've just doen to get it "up and running"

 

2.1 zetec turbo msv3 ecu

and its a mk2 fiesta

so the way i have wired it up is right then? any idears on my air temp sensor?

 

It probably pops and bangs because its not mapped!

 

.. but I would run 1+4 and 2+3 for the injector pairing.

 

Me to.

Clarke have you tried reading the megasquirt manual?

Its online and should give you all the answers you need.

You need to use easytherm to configure an S19 file that you then load onto your ecu. This should get your ecu reading the right temps.

 

this is how mine was run clarke

 

thats where i got stuck i cant make a s19 file ive got my 3 resistances at 3 different temps entered them and got stuck ive read the mega manual a few times about this area but still im unable to work it out hence i asked on hear

 

with MS it doesn't matter which injector you connect together since they all fire at the same time. the phrase "semi sequential" is a misnomer since they are just batch fired and the fact that there are two injector firing circuits is simply for load sharing.

if you can't make an s19 file you can't use MS! mind you setting up MS is a significant undertaking and not easy as is often made out - very interesting though. you'll find it much easier if you get a stimulator to play with it first

 

Correction: they CAN fire all at the same time, they can also ALTERNATE. Sometimes you have to run them alternating, depending on the size of the injector. I tend to run anything I do as two squirts + alternating. That then gives you similar duty cycles as if you were running fully sequential.

The two circuits are not for load sharing, although that is a byproduct. The purpose is for the above functionality.

 

yes my error (it was 12.45am!) but the essence of my point remains: whatever you do with MS in terms of injector firing, if they all fire the same number of times per engine cycle, changing which pairs of injectors that clarke connects in parallel will not cure his problem!

 

Clarke, i'll try and find/write you a quick guide to loading your S19 onto your MS.

As said before, best thing to do is get the car in a state ready to map, supply some grub eg takeaway pizza and have a PF night of mapping with the usual suspects. I'm sure we can get it up and running nicely.

 

sounds like a plan mate lol ive got the car to idal now in fluters now and then but it does run its my gfs bday coming up soon so ill have to put it off a few weeks then ill get some cash 2gever and arange a night how much will you want for fuel?

 

il get a trailer if you want clarke and we'll get it up there one week end, but will need to be back before dark as no rear lights

 

ill sort the lights. what ones dont you have? lol sounds like a plan

 

Clarke,

Have you got a wideband? Has the car got any ticket/tax?

No need to bring it to me. Just arrange an eve with the east london crew, chip, jay etc and i'll pop down too on the bike.

 

sounds good.

Clarke, the have mo rear light, fog lights, left indicator makes central locking lock/unlock

 

ive got a wideband fitted to the car its taxed and tested (till the end of the mounth) but im not insured as of yet. gota sort out my gfs b-day present first

 

im up for this ive always enjoyed mapping ms so count me in as part of the crew doug

 

Committee calibration!!!!

 

That way there is never just one tit to blame if it nukes its self.

Only joking clarke!

You coming?

 

No i'm sure you guys are more than capable

 

oh come on it normally turns out to be a good event/meet happy occasion and opefully a car mapped

 

this sounds like a fun night do you all wanna cram in the fez tho lol wud b funny to see

 

itll be a grin mate

 

 

you already know chip doug is a tall stocky lad im also 6.2 19 stone so i think we will fit in

 

I'm 6'1" and 23 stone so no chance

 

shit i bet one of us can fit in the boot and make sure the lamba probe stays in the pipe and imagine what load we would create up hill

 

sounds like you'll need to weld the shocks to cope with these in the car clarke lol

 

ur getting strapped to the roof rack as our private mapping road patrol spotter

 

lol, ill just sit out the sunroof, i done this in xrt_si's cossie with its previous owner when it come on boost at 30psi, couldnt get back in though
