Quick Question to a little problem...

[Snuff]

Guys (& Girls);

Does the CB7 come with a limiter? A Govenor?

I ask because at about 170 kph, she stutters and she won't go any faster than 180 kph. No matter how hard I try.
(For you Americans, 180 kph is around 110 mph.)

My White CB7 doesn't have this problem as I've had her up to 220 kph without any incidents.
But my Blue EX is still stock.

Assuming that you are trying this in an automatic CB7, yeah there is an electronic governor in the ECU.

There is no govenor on the EX model.

on my 92 lx the governor is set at 112mph.. ive hit it a couple of times..

There is no govenor on the EX model.

UMM ON MY 1991 EX There is a govenor, hit it at 115mph, but when i got my intake and igntion, govenor disappeared. I know a few people on this site that have govenors on their EX

Neuspeeds P chips can get rid of governors on VW's. I'm pretty sure they offer chips for Hondas too. Check out NEUSPEED.com. You can always contact them and ask if their chips can solve that.

I thought there was too...Or is it possible the engine does not have enough power to get you past 115...

That weird... my car is at 120mph with some help behind it....N.O.S.

There is a speed govenor on EX models and all other models. If it was sold in the US or Canada then there is a speed limiter. I've hit up to 125mph in mine with a factory ECU and distributor but then the ECU cuts fuel injector activity until I slow down to about 115 or 120 and then they start working again. When it does this, I'm onnly at like 5-5.5k in 5th gear so I know it would go faster if the speed limiter wasn't there. I know HKS makes a device called "The Defencer" that bypasses the speed govenor, but you could also just get a modded ECU or standalone.

Power?

As far as power was concerned, there is still plenty of it because the lurch from no-gas to full-gas is phenominal. Besides that, the tach only reads all of 4800-5000 rpms.(-When I get to between 170-180 kph.)
I've had my F22A1 at 6100-6200 on a regular basis even though she has an automatic trans.

As was said earlier, I am thinking that it is WRT the ECU, now that you all have put forward plausible suggestions/theories. (Why? Well, because a mechanical limiter on a transmission? I have not heard of one, but is it possible?)

A question I have about changing the intake or ignition is why would those have an effect on an electronic govenor?

(Just asking guys. Many questions, no answers, so I come to CB7Tuner and ask.)

Just so you Americans know, in case you didn't, the EX in Crazy Canuck-land is what you guys have as the EX-R.
The EX-R here is your SE I think.

[ACCLUDE91]

na, there's no mechanical limiter. The ECU gets signal from the VSS. When the ECU picks up that VSS signal showing a speed greater than about 170kmph, it cuts off the fuel injectors. It does this for both auto and manual Accords.

And BTW, we have no EX-R's here. The SE's don't have the factory fogs and ather features that the EX-R's do but they are a close match. Your EX model is probably closer to the EX models here.

i have had 3 accords (still currently have 2 of them)
91 LX auto gov at 117
91 LX 5 speed gov at 122 R.I.P.
93 DX 5 speed gov at 112

my buddy has a 91 EX auto all stock as far as we know and we have had it to 155 mph and the tach was past 7,000 mark. it seemed that there was still more speed to be had. as for how we knew how fast..... those electronic devices on the side of the road that tell you your speed only have 2 digits but if you are over 99 mph it will flash 00 then 55 for 155. not long after this the tcu went out so we threw in another 91 LX ecu and tcu and there was still no governor that we could find up to the high 140's.

my conclusion

[SMseagren83]

155mph? umm and u didnt break anything? 7000's rpm??? dont we have a rev limiter that would have kicked in which cuts fuel? All that happened was ur TCU went out? hmmm......interesting

this did not cause the tcu to go out. not that we believe anyway. the tcu is a common problem in the accords. yeah, my conclusion is that this particualr accord didnt have a rev limiter or governor.

[KillerCam282]

The difference between models and speed limiters can be the reason why there are a few different ecus for the CB's.
