    Sorry, we don't have copies of the URD tuned base tables. Perhaps call URD and select the tech support line, you should get Gadget.

    Regarding erasing the table in the MAPECU3, the only way this...

    Hi, I am pretty sure we replied to your email you sent back on the 8th and then the 19th. There are no jumpers to change in a MAPECU3 so it should just be a matter of wiring up and running.

    We usually recommend a new sensor. If you disconnect the OEM sensor from the OEM ECU you will probably get a CEL. The knock sensor is not a resistor, it is a microphone, so we don't think a...

    I believe the 2000 model year is the 1998-2000 version which uses the normal narrowband sensors, 4 of them I believe. The idea would be to run the pre-cat sensors through the O2 Adjust function but...

    Good to hear the wideband is working OK.

    That is correct, your scanner has no idea you are making changes to the ignition timing as it is happening right before the ignition coil and spark plug....

    Some of that is not quite correct. You don’t need to toggle maps for open and closed loop tuning. The O2 Adjust function is designed for the stock O2 sensors but we haven’t tried it on the 1UZ. It...

    We haven't heard back from the other member. We can have a look at your log if you are able to log the event? Could your IAT be suffering heat soak?

    You have to wire 2 wires. The OEM MAP sensor output is connected to a spare MAPECU3 analog input configured to "FCD1" and then you configure a MAPECU3 analog output also to "FCD1" and connect that...

    You can edit the pressure scale file MAP_CONFIG.cfg if you really want to but we might need to provide advice on the layout.

    Ok, nice and simple. The MAPECU3 FCD can be wired in the same way and you set the clamp voltage to 4.3V. There is a clamp release pressure too which allows you to reinstate boost cut if you boost...

    You can probably use the FCD function with the benefit of overboost safety function. How is the boost cut module wired into the vehicle?

    I didn’t believe even e85 will cause you to use double the fuel volume so I think 2150cc is too big. You might want to consider using the flex fuel option because it seems not all e85 is created...

    Good question. Yes, that guideline is for regular gas. You need more fuel when running e85 so you can go bigger again. Just be aware of the limitation if you want to run regular gas and e85.

    Yes, that's what the different pressure sensor selections do. The only problem is that if you have a tuned table setup for the other pressure scale you need to retune it for the new pressure scale. ...

    I think I should warn you that the IS300 will be a very difficult first tune for someone new to this. The OEM ECU is very fussy about how it is tuned and you really need a OBD2 scanner to read the...

    Nope, we have run longer cables for vehicles with the OEM ECU under the bonnet. The usual rules apply with soldered wiring and definitely not those horrible vampire clamps.
