Modding ECU clock?

**bboipinoy112** · 10-05-2004, 08:56 PM

heh. this guy is nuts man.

EDIT - and if you want to know how to shift passed 6k rpms in our 3geez honda accord. i know how, and its not that hard to figure out how to do it either.

**accordlxi2.0** · 10-06-2004, 07:33 AM

i still don't under stand how this is possible.
i forgot the name of the e-tranny it came out in like 91 or something, it's the kinda where it uses a ecu to adjust to your driving tactic's.

i know the sable has it, but like i said i was wrong . . . . .
my other 2 3g's did'nt have a e-tran's so i don't know why this one would be different.

fellas, it was in 1990, the 4th gen, they brought the sports tranny. Or to say the shitty auto with sports mode and all it did was under full throttle (pedal to the metal) it shifted at 6K. thats only if u had the sports on. ANd our 3g trannies dont have em. THey are just controlled by how hard u pull on the TV cable, hence the throttle and its duration. I am not a geek about autos. but all there is to it is that its not controlled by the ecu. PERIOD.

PS: Mods, if you guys can lock this stupid of a thread. please do and if any other threads do arise in this manner, please delete them. Its a waste of our time and space here to answer these fellas who dont wanna listen.

Ahahahaha. Get 'em Praveen.

Haha this is so funny, I can tell you boys when I pulled the auto out of my 89 SE-i the only electric wires connected to that were the backuplights and the cables going to the starter. And If you can't control where you're auto is shifting you're not driving it right, just floor it till u get to the point where u want it to shift let off the gas slightly it will shift and then slam it again. Easy. I've done with my 86 LX-i hatch and my 89 SE-i Coupe. In fact that's the only way to drive it, till it breaks.

OK let me enlighten some people. Fuse 11 under the hood is the ECU/Clock FUSE, not the ECU clock CHIP. The / between the 2 words indicates it provides power to the ECU AND the clock, there is NO ECU Clock. When you pull the fuse you RESET the ECU's memory (stored faults / PGM FI light) and the DASH CLOCK's memory by temporarily removing power from them.

In doubt see p 12-16, 15-71, and 25-13 of the downloadable service manual found HERE

Praveen if this thread bothers you so much dont reply to it. When you become a mod you can close all the threads you want that dont meet your standards or dont want to buy into your beliefs. Heres a concept...........If they dont want to listen to what you have to say then stop talking. Don't take offense Praveen, its not just you whos wanting threads locked and the like. Some of the attitudes on the board are getting a little stale

Steve you're like the peanut gallery. And Vinny technically you're not correct, every ecu has a clock speed that it operates at and uses that to time it's communications with every device it's connected to, so technically your not resetting the clock since once you apply power to it again it will start operating at the same frequency, but you are stopping and starting the ECU clock.

**accordlxi2.0** · 10-06-2004, 08:50 AM

LOL, i think that's what got him confused. ECU/CLOCK fuse.

smuf if that's all that sport's mode does then that suck's.
when i posted about the tranny that adjust to your driving i was'nt talking about the 3g or the 4th g's.
i'm convinced that our car's does'nt have a e-tranny.

**smufguy** · 10-06-2004, 09:03 AM

believe me, if i was a mod, a whole of this kinda crap would have been cleaned up. It just have accumilated too much that its beyond belief. One guy i know who works his ass off to clean stuff is MIke. maybe other mods do it too, but not that much. Well, if indifference is what people need, well then thats what ill give.

***Vinny*** · 10-06-2004, 09:07 AM

James read what I said carefully. The term ECU Clock was made in reference to the fuse labeled ECU/clock. IT IS NOT A FUSE FOR THE ECU CLOCK.

Theres is nothing technical about what I mentioned, its simple english 101.

A slash or slant or solidus or virgule [ / ] (take your pick of names) is used to indicate a choice between the words it separates.

The slash can be translated as or and should not be used where the word or could not be used in its place. Notice there is no space between the slash and the letters on either side of it.

Removing fuse 11 removes the 12v constant signal to the ECU's stored memory, thus clearing it. Removing fuse 11 also removes power from the DASH clock, thus removing power to its memory. Nowhere did I say anything about resetting any clock contained in the ECU

Because pulling that fuse, breaks the circuit to the ECU which causes the contents of memory to be lost and the ECU clock to stop. That is the defintion of a reset in electronics. So essentially you are resetting the ECU clock. Haha, besides I don't want to get into it with you, I just enjoy messing with you.

Sometimes people need an actual reference to clarify what they are thinking to be properly educated. For some people you can tell then all day but unless they can see it in print for an accredited factual source you are wasting your breath. That’s why I reference the shop manual whenever I can in situations like these.

As far as the "if's" go that may be true. And if my son were born with a vagina he would be my daughter.

Back to the original post.
the three pages I referenced SHOULD clear the picture up.
12-16 - Self Diagnosis Indicator, troubleshooting
15-71 - Throttle Cable Adjustment/inspection
25-12 - Clock input test (Dash mounted didital Clock)

And James said steve was a peanut gallery............

Vinny is 100% correct. Pull that fuse to reset your ECU and I guarantee you'll be resetting your clock in the dash. If I'm correct, you will also have to reset all your radio settings.

Nope, your radio and cig lighter are on the same fuse :P

And all I'm saying is that the ECU has it's own internal clock, not to tell time, but to time communications with different devices and it's own internal calculations. If you understood how an information bus worked you'd understand what I'm saying. It's all good though.
