Link G4 map for a 4age 20 valve

[ATAl]

Hi, has anyone got a link g4 map for a 4age 20 valve that they would like to give me a copy of?

Using the link default map all I can do is make the engine fire out the intake, which while looking quite awesome doesn't make the engine start.

Ideally I need a blacktop turbo map, but I think any 20 valve map will get it started.

Cheers.

You sure you've got cam timing right?

[ATAl]

Pretty sure, all the marks line up, but they are aftermarket cams so perhaps something weird is happening there.

I was looking at the dizzy CAS and there's the 24 teeth wheel at the front which I take to be the NE / crank signal and I'm using that for trigger 1 on the link and there's the G signal wheel behind it which I'm using for trigger 2, but the G signal is nowhere near it's sensor when the engine is at TDC which seems wrong to me.

Has anyone got a picture of how the CAS should be when their engine is set to TDC?

last time I made a car do that was when i had the sparkplug leads on back to front ie. i had #1 lead on #4 cylinder etc. I had incorrectly assumed that #1 cylinder was at the flywheel end of the engine.

My mistake with similar results, when I wired the Link, I assumed I entered 24 teeth into settings, but I didn't press enter and it didn't stick. I spent two days assuming that I set it all right and not even looking at that part of the screen, checking all the connection wandering why the error rate is so high.

there will be 2 sync's on the cas. are you using the one that is closest to lining up when the engine is at tdc?

you can use trigger offset in pc link to adjust the base timing also. so if this number is way off its not gonna help at all

Using the link default map

The G4's do not come with a base map from memory.

they come with some numbers in there, but it is in normally not capable of starting an engine.

i have a map that might get you going. will be far from ideal tho

Pretty sure this is wired correct, not using the distributor, but I'll double check this as it can't hurt.

Will check this.

That would explain a why it won't start

What's it off? Might be worth a try.

Just noticed something that seems dodgy, when the engine is set to TDC, the distributor is firing cylinder 2, this seems wrong to me, could someone with a blacktop check if theirs is also pointing to cyl 2 when set to TDC please.

It should not point to 2 on TDC.
Most likely your cam is off (as you cannot put black top distributor in wrong way).

sounds likely.

When you set the cam timing did you notice that as well as the marks on the top of the cams lining up with the camshaft cover,
the dot and line need to meet in the middle of the two cams,
as there are two marks on each cam.

All the marks (the dots and the lines) on the pulleys line up, but do you mean there should be markings on the cams themselves?

These are aftermarket cams and it crossed my mind this morning that the slot for the distributor could have been cut the wrong way causing it to point to the wrong place, I'm going to go up to pick a part tomorrow and hopefully the blacktop there still has it's cams and I can see how the distributor slot lines up.

Also, it looks like the cam gears on the blacktop and silvertop have the dowel holes in different places, it's possible the cam I've got is supposed to go with a silvertop cam gear, will have to check this at pick a part too.

I guess I'll also have to pull off the cam cover and see if when set to TDC the cams actually are looking like they are in TDC, grrrrr.

16v 4agte.

what cams are they? they would have to be complete knob heads to cut the slot wrong.
how is the ignition set up? waste spark? two twin coils? i once plugged the wrong twin and caused awesome fire balls out the intake too.

Seems like I've been a complete retard and mis-interpreted the service manual, where it said "put the cam knock pin in the side of the cam wheel without the 5" I've interpreted this as put it in the hole opposite the one with a 5, where after looking at how the cams line up it seems it ment "make sure the 5 is facing out".

So I've fixed that now and the dizzy lines up, which is great, but after turning the engine over a couple of times it jammed, could be a bent valve but I there's a bit in the bottom end which I've always thought might be a bit dodgy and it is probably this, well I hope it is, then it's a 5 min fix vs pulling the head off and new valve. So will pull the sump off to have a look.

Anyway thanks for your help everyone.

when i was setting up the triggers on my G3 i had the engine jam up too, it was because of two of the injectors staying on and filling the cylinders with soo much fuel that the engine couldn't turn over.
