Anyone fitted esgi system

[neilt]

Hi just having troubles setting up the esgi with magic mixer on a mercedes e240.
all fitted now but dont really understand what to do with the software.
anyone local to bagillt in north wales who is willing to have a quick look.
Can get it to run but dies and cuts off no 3 cylinder,doing something wrong but god knows what.
Help please before i give i go mad and the wife kills me.
Many thanks in advance.
Neil.

Mercs have a little trick that fools lots of people. If the petrol ECU detects a fault, it deliberately shuts off a cylinder until the next time the engine is started, even if the original fault has gone. The first thing you need to do with the software is run an autocalibration which involves holding the throttle steady while the system switches between fuels and sets the multiplier. No doubt someone more familiar with the esgi system will be along soon to tell you how to fine tune it.

God that was a quick reply.
That mercedes little trick is driving me mad,im going to wear out the ignition the amount of times its been off and on.
when i do the auto cal i just leave everything alone no rev, lights,or touch the steering.
but still sounds like a tractor.
Thanks again Neil.

The quickest way to get help would be to post ascreenshot of the ESGI display while running on gas. Else we'll have to get into twenty questions. I'll start with one - what size did you make the injector nozzles?

[john_d]

have you ran the auto calibration yet?

[neilt]

INJECTOR NOZZLES good question,not touched them so far,so standard.
have run the auto cal until im blue in the face.
just having a lesson on how to do a screen shot then will nip out and have another go.
bit over my head with this so Thanks for the help.
Neil.

They are supplied "really small" and require opening out for most cars. This is an RTFM item I'm afraid

Why isn't your supplier helping?

I got the kit nearly 2 years back,its been sat in the garage since.
cant even remember the name of supplier it was an ebay job.
any idea what size i should drill jets to.
the car is a merc e class 2.7 177hp.

2.2 - 2.3mm for the injectors

the fact that injector 3 works ok on petrol but disappears on gas would make me question if the no.3 cylinder is wired correctly.

[Gilbertd]

Unless the egsi autocal is different to others, I think you have to take the revs up to around 2,500rpm for it to start and then hold the throttle steady while the revs rise and fall.

its the odd one out as you run auto cal on idle.

[neilt]

ok thanks for advice will drill injectors,and check wiring,then try auto cal again.
what pressure should i set the magic 3 mixer on idle.

[sijones]

as john has pointed out, the wiring for cylinder 3 (petrol injector) is backwards, need to swap them around.

Then you need to get the nozzles the right size, these are in the injector rail not in the manifold, then do an auto cal, once that completes at idle then we'll talk you through the fine tuning!

leave it at the moment, don't complicate things too quickly

[neilt]

head in a spin now what do you mean by wiring backwards on no 3.

[neilt]

ok getting somewhere, just found injector hose on number 3 crimped.
run the auto cal sounds much better.
so it revs ok now without cutting no 3.
so what now.
Thanks once again.
Neil.

[john_d]

what "Deflection" did you get after the autocal?

next thing i'd do is hook the laptop up and take it for a spin on gas and see how it runs, this will also then give you the map needed to make any adjustment.

how does the gas times compare to the petrol times on idle?

[neilt]

Taken out for a spin on gas,goes but lack of power and k light on.
something going on
cyl 1 2 3 =6.9 ms
cyl 4 5 9=11.7 ms
on gas.
even on petrol its still a touch rich on cyl 4 5 6
set the mixer on 1.40 bar is this ok.
have been trying to do a screen shot but cant because son has gone out, and im @!## on the pc.
could one of the lambda be shot.
both seem to be working on petrol ok,but on gas one goes sky high the other goes lean.
will get my lad to put a screen shot up when he comes in.

[rossko]

Have you addressed your nozzles issue yet, what size (or assortment of sizes) do you actually have????

If you mess with the pressure or nozzles, you should re-do the autocal.

could one of the lambda be shot.

I wouldn't have thought so, but it depends what "working" means.
