Guys thought Id post here. (as running a E8)

Im trying to get the car going.

but she aint.

So Im assuming the issue I have is timing.
I have a timing light, but it wont pick up any signals from any leads.
(CDI on the leadings and LS1's on the trailings)

Is it just my light it to budget, or something more complex ?

Any idea's. how can I set up my timing with no timing light ?

Cheers Anth

PS getting spark, good fuel pressure. runs rough as.
reads rev's fine, just dont know timing !!

 

also another question to go with my timing one.


On a rotor in the fuel setup -> injector current setup.
there are 4 windows that cover injectors
1 to 6
7 to 8
9 to 10
11 to 12

Do we only ever look at the first window as we typically only run 4 injectors ?


how do you define the current when we have all 4 injectors that require different curents ? EG
2 primaries at 2.2ohms
2 secondaries at 4.5 ohms

So do I just set:

1 to 6 = 5amp
7 to 8 = 2amp
9 to 10 = 2amp
11 to 12 = 2amp

guys any issues of using a 92 trigger angle ? havn't got it fully refinded down yet but thats what Im getting so far

Also out of intrest why does it alway read BTDC when really we want it ATDC to work with?
(as leading is -5ATDC and trailing is -20 ATDC)

 

Still cant get the bloody thing to idle, will try again tomorrow night with a mate.. (as I cant crank and do timing at the same time)

BDC thanks heaps for the new map. Had a few issues which came down to putting all the stock sensors back on the map.

but for locked timing... **** me didnt work for me.
while cranking needed a trigger angle of 97 ???

It wouldnt run no matter what I did (was advanced about 50deg). I had a play and thoguh **** it Ill put it back to 65 to see what happens and bang she's now idleing !! happy as larry now

guys a bit of a update

Eventually got all the piping done etc. Ive now got the car home and the base map I had before wont start the car.... (urg)

So im starting at scratch and going to check the timing etc etc. Anyone got any reason's for why this might happen.

Also it is winter here and the correctional value for the coolant on the data page is at 36% ... does that sound right ? its only mid 20deg. (68 Far' your scale)


Also one last thing is there a way to copy thr text fuel map out of the haltech, so I can put it into excell ??? (I want to compair other base maps and see what level of fuel I need as I think Im currently to lean to start the engine)

And one last one. Cladio in your base made you satge the secondard injectors as common. But DBC does primary hold. Is one way better then the other ?

Thanks for any help ... so fer haltech and rotor tuners where I am !!

 

I have copied maps in and out of excel from memory, don't think I had to do anything special. I prefer common mode staging, as duty cycle displayed is actual duty for all injectors. Just easier to see for me if things are maxing out or in a range I expect.

 

Thanks mate, if thats the case I see it being a better way. I will try to have a play after al the family leaves. I shouldnt have to change up in the map correct ? just change to common mode ?

As for coping the map. If you go CTRL A (select all) it opens anolog input function..... so makes it bloody hard to copy.


does anyone have some tell tail tricks for when it wont idle for when its either to rich or to lean ? Im guess it floods on to rich and just stops running when to lean.

So what the hell do backfires in the equation mean ?

 

sounds to me more like there is still something funky in that ignition setup in terms of signal polarity and trigger tooth settings
i would be checking to see if either leading or trailing is drifting with RPM, indicating the setup polarity is **** up

and what exactly is your injector selection again?

 

Primaries are Siemens 3145 = 750cc (3.2 ohm’s)
Secondaries are Bosch 0280150837 = 1580cc (4.7 ohm’s)

Bumps would have to agree... But while the car was at sanders racign they got it started and running, but they said theyhad a ***** of a time but once it warmed up had no issues.

So this is the main reason I think its cold start related maybe. (I dont really know the trick to cold starts)

Also Beef is being the champion he is and lending me his timing light again so will see what I get... but like last time its nearly useless as if its not running checking the timing isnt going to help me much.

 

please comp check it !

the backfire is indicating maybe its blowing out the spark ( and its going off sympathetically in the exhaust )

but its more a sign of the timing being out ( drifting or seeing phantom trigger due to ignition settings )
or even of significant RFI ( use the log to determine )
but can even be chipped apex seal !

 

sigh... ok will try to find a compression tester. Got any advice for one from a repco ? dont want to spend to much... saving for a holiday. guess even it it doesnt read spot on the psi as long as all pulses are the same it should be right.

(also it only did the backfire when I richened the whole non boost map up by 5%)

Will check the RFI with the log, in the past its fine. And the wiring for the coils / cdi is no where near the CAS setup

Phantom trigger could be a issue, but really will only be able to tell once its running... which haven't even got that far ... lol (its the same bloody map... run FFS)

Also this is a screen shot after the engine was running for a few seconds. Is that coolant correction right ??

(quick data log attached as well... is there a way to get the O2 sesor to log AFR not just the mv's)

 

you cant trust the lambda meter till its fully warmed up
as such,, indicating lean when cold is normal enough
just by observation of adding fuel making issues worse,, i would comment that it appears you already have too much fuel


coolant correction % is normalish,, and depends lots on the base map and injector selection
you can always scale it to less and try again
BTW,, are you staging the fuel pumps,, or running both full time ?
have you observed whats happening with fuel pressure?
its common enough for the reg to drift ,, or for issues like too small a return making for excessive pressure with two pumps

------------
anyhoos,, cant spend more time here ATM as have to run around,, one of our rotor friends has had a big accident ,, and i have to wingman him

 

sorry to hear bumps.

Cool well beef lent me his new timing light so will go through everything this weekend

When he dropped past I got it running for a good min or so, she's hell rich so I think Ill drop the fuel about 5% in the no load maps and see how she goes. Just had to use heaps of throttle then back off, then heaps and back off. Should of tried to get a data log but didn't have the lappy.

Been playing with the rest of the brake wiring and got that all complete, so will hopefully have a uninterrupted weekend to try and get it all sorted !!

 

if you're stabbing teh throttle to get it to start then the prime map is too low and you're compensating by adding fuel with throttle pump circuit.

 

Guys thanks for the help, but I think Im just going to give it to the tuner i have lined up to do it all for me !! lol bit out of my league just yet. hopefully onces its all tuned I will have a greater upstanding.

All going to plan should be done about the 21st of July so will keep this thread updated

also one last QU

in the data logs anyway to make it show AFR ? not just the Mv's ?
