timing issue with coil on plug

[bens_cab]

hi guys

msns-extra 029q

vw 20vt coil on plug wasted spark

i have a problem got the car running but its really rough missing ect ect
even tick over is rough

im using a vr sensor

trigger angle 60 deg

trig a 5
return 14
trig b 35
return 44

60-2 wheel on the crack the car is running really rich so im starting to think that its the timing a mile out really need help now as ive been doing this for ages

the engine has come from an audia3 into a mk1 golf

any ideas

[bens_cab]

forgot to mention

i have a good rpm reading in megatune but my data logs are doubleing the rpms???

[jsmcortina]

Your constants must be set incorrectly. Make sure you have the right number of cylinders and four stroke.

Do the rpm indications on the front page of Megatune match that in Tuning->Realtime display ?

hi the rpms match in both

ive got the constants set 4 cylinder 4 stroke 4 squirts per cycle
12.2 and 6.1 required fuel

its defo running rich its used a gallon of petrol just on tick over since yesterday and ive only run it up for an hour

i have high impedance injectors ill try and post my msq

could it a mismatch in my code

my ecu has 029q flashed to but everytime i load the ini it say 029i in megatune

i dont get any error messages but my datalogs are coming back black its not reading them now ??

why me

[jsmcortina]

If Megatune gives you a signature error then you are asking for trouble, you must fix it before trying to use Megatune or the data sent to the Megasquirt is likely to be corrupted.

If, however, you are loading an older MSQ file that was created with 029i then you will be close but you must use the "review" feature to go over all settings.

got the 029q code to work now megatune has a different layout is this correct

also i wasnt running alternnating injection so will try tommorow as see what happens

[jsmcortina]

Yes, the menus were re-arranged by 029q. If Megatune starts up without signature errors and shows the correct version at the top then you are ok.

Double check your settings, I've never heard of anyone showing twice the rpm before.

Also, as you are just starting, grab 029q2 as it has the default temp sensor tables. 029q had the wrong ones in error.
OR, grab 029r (test) which resolves a problem I had with poor crank rpm pickup.

hi

still having rich readings what i did notice in review mode is that my connstants 2 are reading like 31 required fuel but im not that am i

if i enable table 2 and set them contsants the same as table 1 will that help

[jsmcortina]

Check the fuel table selection menu, you should have injector 1 and 2 running from table 1 and GammaE should be on.

Are you using 029q or 029q2 ?
029q had an error in the supplied air temp sensor table causing rich running, 029q2 has this back to normal.

The MSQs are identical between the two.

if i just upgrade to 029s when i download firmware do i need to have the ecu on ie connected to the car i or is it something i can do in the comfort of my bedroom i have 029s on my lap top

wasnt sure what to do with it as bill shurvington did my ecu and firmware or can i manually do it ???

sort of all new to me so any advice or guides would be good my eyes are bleeding from so much searching and reading


Ben

You can only download firmware while connected to the Megasquirt.

Changing from 029q to 029s "should" be as simple as:
save your settings in Megatune
close Megatune
double-click on download-firmware and answer a few questions*
open Megatune
reload your settings

James

*are you upgrading from standard Megasquirt code" say N and life will be easier with no case apart and messing with boot jumper

sorry for being dense do this with the ignition on or off

also will i need to run easyfirm for my vw sensors to
