It should pop right out with a slight tug. To accomplish this take a small safety pin and carefully push up the plastic tab that holds the pin in the harness and lightly pull on the wire on the other side of the connector. On the ECU wiring harness remove the yellow protectors, they pop off with a small screw driver. On OBD1 it's used for the special diagnostic test mode. I used the pin from TE2 (E10-19) which is not used on OBD2. This will require you to either cut a wire off of the ECU harness or find a donor pin from another harness.

How to get the primary O2 sensor heater functioning: Since there's an additional pin needed for the new groundwire you will have to find one to use. It can cause the car to run very rich at idle.Īdding the groundwire to the ECU harness fixes the problem. This happens when the car is cold or idles long enough (4-5 minutes) for the sensor to cool off. This will prevent the car from entering closed loop operation when there is insufficient heat from the exhaust gas to keep the sensor at operating temp. Not having this ground wire causes the primary O2 sensor heater to not function. 2) On OBD2 cars there an additional ground wire that's not present on OBD1 cars. Failure to do so will result in a MIL from the secondary O2 sensor. 1) Like any OBD2 car you will need to run an O2 simulator if you have a catless downpipe installed. In order to get everything working correctly the issues below need to be addressed.
The only thing I know of that doesn't work is the TRAC system. Simply disconnect your OBD1 ECU from the harness and connect an OBD2 ECU.

How to upgrade an OBD1 car to OBD2: Installation of the ECU is plug and play.įind great deals on eBay for OBD2 Cable Toyota in. Below is after tuning the OBD2 ECU with the SAFC was completed. No other changes were made.Īs you can see the problem is no longer present. Below is another FJO wideband capture after installing an OBD2 ECU without any SAFC fuel correction. It will also allow you to monitor and datalog engine parameters such as timing, short and long term fuel trim, coolant temp, TPS, intake air temp, engine load, vehicle speed, air flow rate, and O2 sensor voltage. Note: Lagtime also discovered that this problem could be resolved by using a Greddy E-Manage with optional injector harness to raise the injector duty cycle.Īnother benefit of running the OBD2 ECU is you can connect an OBD2 scantool to read and clear MIL's. After doing a bunch of research I found that installing an OBD2 ECU completely resolves the problem.
Attempting to add fuel using an SAFC-II or similar piggyback does not resolve the problem. Further raising the boost causes the problem to worsen.
The example below is from an FJO wideband datalog captured from my '95 TT while doing some street tuning at ~18psi. Summary: There is a known problem with the OBD1 ECU which causes stock twin and small single cars to run lean between ~4-6k rpms at high boost.
