Advanced the timing ep91 na

[Kaaaty]

hey all i advanced the timing to no change in feel, but have since found out i have to bridge something in the ecu. i was wondering who else has advanced their timing and if they could help me out.

cheers

I tried advancing mine and it felt more sluggish

[LukeSR]

Guess i wont be doing this then

[Kaaaty]

did you bridge the ecu amjad

[Amjad]

Nope, I've never heard of bridging the ECU, just to rotate the dizzy clockwise a few mm.

[Kaaaty]

ahhh i rotated anti clockwise i thought you rotted towards you lol ill try the other way. i am under the impression that the ecu compensates for the retarding or advancing so you need to bridge certain parts while you advance or retard for it to change. cheers for your input amjad ill try the other way and tell you what found

[Amjad]

I dunno I didn't try anti-clockwise, quit while I was ahead

Yeah do let us know how you get on

Dont do it without a timing light can easily be over done causing pinking + 2mpg

Bridging the port does two things iirc.....the idle will rise and then fall (meaning your icv works) and does one other thing which i forgot lol

also make sure every single thing is off when you mess around with the ignition (including the door open light)

then put the timing light on and make sure you start from the base settings (white sticker under the bonnet shows this)...tbh its such a minor mod will hardly feel anything from it with the age of all the ignition components its probably already off so set it to standard and leave it

Id tinker with something else unless you do it on a dyno where you can see where the most power is made etc etc

i have advanced the timing by about 2-3 mm the car is noticably nippier and revs until im over 30 in 1st now compared to redlining bang on 30.

do it 1.5mm not 3mm i noticed a bit of improvment but nothing to write about. i found just polishig the inside of the inlet manifold much more effective..

[Amjad]

Did you bridge anything? And was it clockwise or anti-clockwise? lol

[steed]

shouldn't have to bridge anything, just move the dizzy far enough that even when the ECU tries to compensate for the shift it's been advanced/retarded outside of the variable limits of the ECU

[mk1kurt]

no bridging at all

cant actually remember what way ive slept since then lol

but ill check it out as i tipexed a line on th dizzy and the head incase out went wrong

[Kaaaty]

clockwise and no ecu tom foolery
