It seems to me that your ECU is in limp mode from the SAI system - or in limp mode from something else that was "deleted" in the ECU programming. Based on what I have read it is possible to turn off the SAI codes from triggering the check engine light, but the limp mode condition still prevails...
Good to hear that you can rule out the MAF tube diameter as being an issue - although that would have been an easy fix. This is great info for others doing the same swap in the future.
I would keep at it because you must be close to figuring it out. A lot of people have given great advice in...
It seems worthwhile in my opinion to do the easy troubleshooting step of measuring the inside diameter of the air tube where the MAF mounts for both a VVTi Land Cruiser/GX470 and a VVTi 4runner/LX470. They are probably the same, but what if they are not? For a data point comparison my 05 Tundra...
Does the OEM intake you are running match the donor ECU? Meaning, both the ECU and air intake assembly are from a VVTi 100 series?
The reason I ask is because there might be a difference in the diameter of the MAF tube between a 100 series and GX470/4runner and the correct diameter is needed...
I have been enjoying your build thread and will throw out a few thoughts I have. Thanks RivMan for asking for a rundown of your setup because it is helpful to see to provide input. There are two things that jump out to me.
Is the issue fuel supply related? To my knowledge the VVTi Land Cruiser...
For used parts I’d try Proffitts first. Jeremiah, the owner lives close to Gunnison.
Classic Cruisers is proud of their parts and price accordingly. Metric is also proud and may not even want to sell the parts.
Potential buyer was a no show on picking up the engine and I am wondering if it was actually some sort of scam deal... the buyers phone number stopped working on the day he was scheduled to pick up after not showing up for a week due to a rental truck breakdown. Google voice perhaps? All and all...
