I have a 94 turbo, vtec prelude, only running 6lbs of boost and using a hondata S200B with all options for management. I finished the turbo install yesterday and went to take it for a ride. Whenever the car starts to boost or right about 3K rpm, the car just hits a wall. It does not cut off, but the fuel cuts. Its not like i am bouncing off of the rev limiter, the car just rocks as if you are popping off the gas petal from wide open throttle even though i am only 15% into the throttle. I searched and no one with a hondata had a problem like this. Can anyone help?? The reason i blame the management is because i have trouble shooted everything else. Thanks for any info.

The engine will only rev to 3200 rpm:

In this situation the error codes cannot be retrieved from the ECU (the check light will remain on solidly). The ECU is in ‘limp home mode’, which means that there is a problem accessing the ROM so the ECU is running off a backup processor. The ECU will use fixed ignition and fuel values. Possible causes for this problem:

• ROM inserted the wrong way around.
• Incorrect ROM for the ECU (see page 6).
• Jumper J1 not installed or incorrect value.
• Bad solder connection to the socket or latch IC (especially with surface mount latch ICs).

BTW you shouldn't be boosting on your basemap

i hope you arent running a basemap trying to boost without a wideband to monitor afr....

"Blackack26" where is that link?? I was not trying to boost on my base map, i was just "limping" home. I am going to tune it tonight. Thanks

Mase

check the hondata box, is it blinking or is it solid light?

I wanted to find out what this problem was first, just to make sure everything was hooked up right. Later today i will be using a laptop as well as a wideband to tune.
I know that car has / needs to be tuned. Is that all it will take to make this problem go away?

solid light, i am also search hondata's site

Mase

if i were you, if you arent getting a check engine light or a blinking hondata light, id hook up your wideband, and see what afr its jumping to. it could just be running really lean at that spot.
