Thread: Timing Advance Processor

If anybody has a timing adance unit for sale I am VERY interested

Thought I'd add to this one instead of starting another thread.

I've bought and received the AEB WOLF 526 from Ron and have just finished installing it. Fairly simple job. The unit itself is next to the cruise control box under the passenger side dash.

With it all wired up and the dummy connector installed (so the wiring is effectively standard) the car runs fine on LPG. With the unit connected but with zero degrees of advance selected the car runs fine on LPG. But when I select any amount of advance it starts to idle poorly. The more advance the worse it gets. What it does is it idles normally but then drops out every few seconds. It picks up again before it stalls but the longer you leave it idle the worse it gets.
Choosing for the advance not to come in until over 1100g/m doesn't seem to help.

Any ideas?
Do I need to take it in to get retuned with this unit installed?

The car is running 10d BTDC in the distributor.

Thanks.

Sounds a bit sus mate they should only advance the timing with gas on and if your running 10 DEG and it runs fine on gas how is it on petty as that sounds a bit too advanced for petty tho im not sure what the settings for your engin are .....

Id be setting the timing for running on petty then see what the advance is at then move the switches on the AEB to bring your advance up from the stactic pety setting as thats what there supose to do the one i have did a good job tho im not sure if it was set right as the instructions i found for a similar one said that were mine was set didnt seem right but i think mine could have been advanced a little more as it seemed to be lacking on gas tho ran sweet on petty i never knew it had the processer till after i had robbed the tank and a few other bits and it was when i was taking out the LPG wiring i found it and started this thread ......

With the decription you have given it sounds like its retarding the engin rather than advancing it and my bet is you have somthing rse about maby go back over how u have wired it il look at how mine was set up and post up some details of it when i get the time as im a bit busy at the moment ..

When I bought the car it was running 12 and after a while I backed it off to 8. Ran fine on 12 but the slightest ignition problem would have it pinging slightly. When the LPG was fitted the installer set it to 10 as he said it was a good compromise.

The wiring is fine. Very simple to wire up actually.

I don't think stuffing anything up would make it retard the timing.

After doing a test drive I have found that the further you advance the timing the more you have to wind in the mixture screw on the lpg unit. If you don't then when you let the clutch out the car judders fairly violently.

The car seems to have more go with the unit. Quite noticeable I think. Next time I tow the camper will be the real test.

I think I've left it at 22 BTDC.

I'll have more time to play with it tomorrow.

Lokka do you know what the dip switches were set at on your AEB unit?
Just wondering if yours was set up with the unit to be disabled under 1100g/m (what is g/m anyway?). On is switch 1 & 2 on and off is switch 1 off and switch 2 on.

I just cannot get this vehicle to idle smoothly with the AEB unit attached.

Runs fine once you are up and going or if you slip the clutch with high revs to get moving.

G`day Justin .

I know nothing of your lpg system( coz you haven`t said ) or of the advance unit and some of this is thinking out aloud as i don`t know exactly what you`ve done/doing .

Sounds to me like your not getting advance at idle from the wolf .

Does it have 6 microswitches and is #5 in the off position ?

Also if your going by figures/degrees first you need to know TTDC .
If you don`t have true tdc the pulley figs/degs mean little .

Don`t know how much you know about it but the amount of total advance needs to be know so`s not to do damage .

If the 22degs you say you left it at is at the pulley ? and you add the mech advance ? and add the wolf advance ( does this unit adjust for 6,9,12 or 15 degs ) ? and then the vac adv ( is this unit able to alter deceleration adv )? It may be too great .

Hi Peter,

The vapouriser is a Landi LSE98.

The advance set by the distributor is 10d BTDC. The TDC mark is spot on as I have checked it before.

The ignition advance unit when set at 12d (to give a total of 22d). I have dropped this back to give a total of 16d and it still gives grief. The only way I can get it to idle without doing the revs dropping out and being unsettled is to disconnect the unit and short the coil wires together (using the supplied dummy plug).

The unit has 6 switches. 1 & 2 set the advance to set in either all the time or only above 1100g/m. Switches 3 to 6 set the advance amount. For a 4 cylinder it is 3, 6, 12, 24 (these can be added together). So should be 1/2 those amounts for an 8 cylinder.

I am assuming that total advance is not affected. Just initial advance. This is just a guess though as I cannot find any information on this or any other unit like it.

As I've said it runs fairly well above idle but just will not idle properly.

My unit has the 6 switches as follows
1 on
2,3,4 off
5 on
6 off

Tho im sure i read somewere that this setting was wrong but the rangie ran fine on lpg Im notsure on what the advance was set at as i never checked it with a light ....
I still think yours has something rse about as its making the timing retard as per what you have posted if the revs drop its retarding and not advancing later when i get more time il find the info i found on my unit and see what it has to say...
