How can i change the ignition curve on my STD ECU?

Hi,
IS there anything out there that i can add to my existing STD ECU to be able to program the advance curve. Jay car make a programmable igition kit will this work.
a few months back someone wrote this,
"..wind about 27 degrees advance into the base timing..don't forget to jump T1 (or TE1) and E1 with a small bit of wire, to disable the ecu retard/advance on idle.. you'll physically notice the difference!"
With the option above it sounds like the ignition is always going to be on 27 degrees. I was hoping to have the option of programming and not fixing to one setting.
It would be good if someone could point me in the write direction.
Cheers,
Ty

to change the timing map would require a programmable ECU - a factory ECU isn't one of those.
the quote you mention means that the base (warm idle, no load) timing is set to 27 degrees instead of the usual factory XX degrees. The ECU will still alter timing based on rpm & load (in the same way that and old dizzi would with weights and vacuum advance).

so is jumping the T1 and E1 a good thing to do or is it just dodgy.
Thanks for the reply's

Jumping TE1 and E1 is purely to SET the BASE timing.
After the timing is set, you remove the jumper.
Most Toyotas run between 5 and 10deg timing with the jumper in.
If you only use premium fuel, you can afford to increase this by a few degrees.
The timing curve remains the same, but its start point changes.

Thanks for helping me with this. So i don't keep bother you and the site can you point me to an article or instructions. I do plan on running 95 or 98 octane fuel. how will haveing a base timing of 27 degrees affect the behaviour of the car/engine. It sounds like you have done it. Would you recomend it or not?
Thanks again,
Ty

You obviously don't understand the combust process or timing so in your case leave the fucking thing alone, set it at base 10 degrees. If u knew what u were on about u would never say to set it at 27 degrees on base.... please for your sake (and your engine) just leave it... I understand I if you were talking about total timing but not base... Anyways sorry but do some research...and leave it alone

I don't need you to direct that sort of language toward me.
27 degrees was an arbotary fiqure which some one else quoted and is obviously not going to be the same in my situation.
Maybe i should of said the words increase my ignition advance instead. I am still learning about 4age's and i asked for some direction on where to go for the resources.
And yes, for the sake of my engine i will try and get as much information from the people who have been there before me.

the 27 degrees was a stupid post.. i saw it and let it slide, hoping no-one would mention it ever again 
an extra 17deg timing in a motor where timing is not all that bad to begin with???
farkin stupid

there is not that much to be gained by changing the base timing..........not really worth doing unless there have been other mods to back up the need of a different ignition curve in which case I would recomend a stand alone computer. my point is on a standard engine you could experiment however the gains are hard to feel when driving the car and then you really are stuck with having to use the high ron fuel. best left alone and search elsewhere for power increases.

hint for a tune up for a 4AGE..
tools 12mm spanner..
timing light..
providing your using 98 octane or the equivilent optimax/ultimate etc, have decent plugs (iridium etc) new dizzy cap/button, and the engine is in overall good condition..wind about 27 degrees advance into the base timing..don't forget to jump T1 (or TE1) and E1 with a small bit of wire, to disable the ecu retard/advance on idle.. you'll physically notice the difference!
if it pings a little back off a tiny bit..but 25-27 you should be pretty good

I apologise but the 27 deegrees was stupid even for a mention...like everyone said all cars run at their best when ther are running like new, so unless u got some fully sick big turbo and cam gears just set it to stock with a timing light, make sure u got new plugs, and everything else is fine and dandy and she run as good as new....

Even if u do advance your "basetiming" the Ecu will still decide how much total timing to run in every situation...at the end of the day you won't get much more if anything at all...and with jap spec cars, they are meant to run on 100 octane so the stock base timing is plenty even with 98 RON...Just my 2c

with the now infamous 27 degrees base timing, once you add the potential for up to 30-40 degrees of total advance, you're going to run the risk of severe pinging, regardless of what octane fuel you run.
the computer will have no idea you're at 27 degrees - base timing is exactly that, the base of the timing curve - it'll happily follow the preprogrammed curve(s) from that trigger point onwards and upwards.
anyway, with the fuly hektik turbo you'll want less advance with the more boost you pump in.

so beigeboy... did you read the 4AGE tech book.. my copy is back home in Aus, but it says the same as the online version in the toymods tech doc linked above..
and i quote..
| Quote: |
IGNITION TIMING......10deg BTDC (w/terminals T and E1 SHORT-CIRCUITED)
|
you do know that THIS is how you set timing on a 4AGE???
oh wait.. so whats your advice on setting 4AGE timing then???

pretty sure its 26 degrees oldcelicas, might want to re-read the manual where it says 27 degrees
hope this helps

oh my bad 
i would love Beigebandits 114th post to tell everyone how to set 4AGE timing the "beigebandit way" instead of the "Toyota way"
