Gnarls I think you may have missed her first posts key statement.
Hi r,
Yeah, I know Tiffany mentioned a 22R engine.
I am just using my 22RE as an example of the pluses of an ECU-controlled engine, whether it’s a RE or an R.
Of course the ECU controls in an R engine is very simple and minor by comparison to the ECU, injectors, and sensors in a 22RE.
Tiffany's reasons for converting a 22R carbed engine and removing the functions of the ECU are “silly” to use OOPs description. I don’t believe the 22R ECUs have ever been seriously discussed as an issue for reliability or performance. In fact, the 22R carb is in my opinion, is overall an outstanding carburetor. It did not like real steep inclines, but in 10 years of serious rockcrawling, I only swore at it a couple times. And the HAC is a very functional feature. By comparison to the options for aftermarket carbs and intake manifolds, and we know what you have to do to get one to work reliably, the factory Toyota carb is awesome!
Now… I HAVE in fact thought about converting my 22RE to a carb'd engine more than once! My experience my current 22RE has been extremely frustrating and expensive to diagnose, test, remove and replace the associated sensors that report to the ECU! I was 10 times happier with my 1985 22R!! … for the reasons most of us have experienced.
Gnarls.
