Speed Limiter - Honda Prelude Forum

H22ATypeS · 02-08-2002, 03:45 AM

Out of curiosity anyone on here know how to remove the speed limiter on the JDM Prelude TypeS ECU? I was racing a GSR and ended up losing because I forget that the JDM TypeS ECU gets cut off at 120 mph! damn that sucked ass......so anyone have any ideas?..help?..comments??

Funny i went 140mph on my 99 Base lude with no probs.

He just said JDM ECU. Yes it can be chipped. I don't know details but speed limiter can be removed.

You may want to look into whether the APEX'i rev/speed meter can do it. It reads in the real speed signal, displays it for you, and after you accelerate past a certain speed, just outputs a constant number to the ECU. I'm not sure if it'll work for the Prelude, but it seems to be a pretty universal type solution. I can go home and try to find the manual for mine if you're interested. I have the old model though (before they switched to the VAFCish look), so I don't think you could find it anywhere. I'm not sure if the new one has the same feature.

Thanks for the replies......I'll looking into the Apexi VAFCs

a Field SFC VTEC controller will remove the speed limiter

I don't want to come off the wrong way..or sound like an asshole...or anything.......but if you guys read my post..I stated that I have the JDM Prelude TypeS ECU...in Japan all cars are limited to 120mph or 180km.......just to let you guys know

ShadowSonic · 02-09-2002, 08:14 AM

I understood, but i went more than 140 without any limiter kickin on.. so how can u say in 5th it redlines.

H22ATypeS · 02-09-2002, 12:24 PM

I didn't say that...1sweetlude did

Ok. I think there is a misunderstanding here. 99Interlude, your car can hit 140MPH+ because it has no speed limiter. 1sweetlude, the same applies to you, there is no speed limiter on your car. 1sweetlude was agreeing with you that both of your cars can go at least 140 MPH.

Now, H22ATypeS's Prelude does have a speed limiter because he has an ECU from a Type S Honda Prelude. The fun stops at 120 MPH. Everyone clear?

I'm clear with that. It sucks having a speed limiter...I took mine to 148 mph., I would've gone faster, but my exit came up...Don't suggest doing this, but if you do, make sure its late at night and the highway has no cars. Also, keep your windows and sunroof closed

Rick Bailey · 02-10-2002, 11:27 AM

why do you close your windows? oh i went 142-143 in my 99 base lude

Kyn · 02-10-2002, 12:49 PM

windows close. Aerodynamics. Open your window and you become part of drag.

Kyn · 02-10-2002, 12:51 PM

unlesss... he meant, close your windows so cops cant' take a picture or a good look at you.

JDM = Japaneese Domestic Market

where did you get your ECU man, was it well worth the money you think?

H22ATypeS · 02-10-2002, 03:44 PM

Well my car used to be an Auto....so after I dropped in the SiR
S-Spec tranny I needed a manual ECU......so I finally located a TypeS one....to make a long story short..yah I felt a difference..but that's probably because I went from auto ECU to manual.
