Hondata problems...
ok guys... I just swapped out my obd2 ecu with my hondata and obd1 p28 ecu... I sent it away to have a base chip installed until I get it tuned at the end of the month... Two Problems... 1. The car will not rev passed 3500rpm and 2. It's throwing the check engine light.. I'm not sure if it's from the second o2 sensor still in the stock cat or not... Inside the ecu there is a jump on the 2 pins.. Could that be causing it?? Any help would be great... Thanks in advance....

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).

You need to check the things they are telling you above. Most of the time it is the ROM is inserted the wrong way but could also be you are trying to load a 2.5v rom into the S200 which will do the same thing.
