I bought a b18cr with a p72 sst chipped ecu, the car(96 civic Dx) has been swapped and everything the only problem is that it won't rev over 7k. How would I fix that?

Swap ecus first to verify your "sst" chip is legit.

What ecu should I use?

Trey

P73 is the Type-R ecu or get a chipped P28 and an OBD2a to OBD1 ecu harness.

I have a non chipped p28, a chipped p72, a p2p and p2e Ecu's if i use the non chipped p28 will it harm something?

There's a reason why Honda never used a p28 with the type r.

Oh ok so I should?????? Use what for it?

If the swap is legal wherever you are, use a JDM ITR ECU. It runs around $100 bucks.

I live in Nashville Tn.

Do you have to get emissions? IF so, the JDM ITR ECU will not connect to the OBDII scan tool. Something to think about. I use a USDM P73 ecu for emissions and then run a OBDI chipped P28 daily with the OBDII to OBDI ecu harness converter.

Sounds like a simple clear answer, the emissions part was my second question thanks trey. I will see if I can get my hands on a usdm p73 and chip the p28 I have. Some guy on eBay told me I should use a p2p for emissions, is that correc,t or should I just go with the p73?

Trey suggested the proper course of action. Your friend in Nashville suggesting the use of a P2P for emissions is misinformed. The P2P is designed for the SOHC 1.6L VTEC engine... rated at 127 HP. Your B18C Type R is rated at no less than 195 HP... maybe more depending on the version. So the question you have to ask yourself is why would a P2P run my big engine correctly ??? The answer is it wouldn't... and then the question is are lucky enough to drive the car around for 75 to 100 miles to set readiness so that you can plug into a scan tool at your local emissions station BEFORE you get a CEL for mis-fires or a fuel lean condition ??? Do you have a cat and a second O2 sensor ??? If not, the P2P will code out and you will fail emissions.

The "chipped P28" means that you have an OBD-1 version of the P2P mentioned above... only it has replacement programming on it instead of the original factory tune. The trouble is, you have no idea what is on that chip. ANY program could be on a 28 pin SST chip... not necessarily a custom tune for the powertrain package installed in your car. Getting it tuned is the safest way to know for sure... and you will make the most power.
