I think they are just busy trying to figure out how much more their stock NAS truck will be worth….

Td5 pedal didn't work?

Don't like this pedal? Pick a different one from their catalog.

Buick = GM, therefore Gen4 GM LS = GM. Is all you have to do is apply a little algebra - math makes sense!

So you're saying there are more engineers and Asians on the Source nowdays?

No, it was just my hypothesis on your above comment/observation on the lack of punditry moaning concerning this engine swap. I can throw some calculus if that would help.

I was talking to my wife about this and she said I could do it if it made the gas mileage improve on the 110

Hall pass

Damn... that sounds like a hall pass to me. LS with VVT and cylinder deactivation from 8 to 4 in a 110. Can your wife talk to my wife. No wait forget it we don't want them sharing any knowledge.

LOL
this is the same old argument as converting to diesel...you'll have to drive a half million miles to recoup the costs!

Exactly my thought. The TD5 is drive by wire and would look more "correct" - from a purely "purist" POV.

Yes, nothing screams pure like an LS3 in a Defender. :p

Not all pedals provide the same input. I am using a td5 pedal for my EV and it's got two potentiometers which provide the inverse value of each other, and the sum if the two always comes out to 100% of full throttle as a checksum. The ecu or controller may not be able to support this and he said "plug and play". Even if you just used one potentiometer and ignored the safety feature the voltage range may not match and may be difficult to configure it something.

I do have a Td5 pedal complements of surf110. I took initial resistance measurements of both the GM Silverado pedal and the TD5. I have yet to graph these in Excel to verify the both pedals have the correct ratios. I also have to locate the proper connector to mate to the GM harness for an adapter to the TD5. I will get to it, just don't have time right now. The TD5 pedal doesn't just bolt in. Different pattern.

The Lokar actuator is manufactured by Williams Controls and is a Hall Effect device. No potentiometers to wear out. Williams Controls supply the mobile industrial community. CAT, John Deer, ...

I can get you the connector info. Maybe tonight otherwise one if these evenings. Ping me if I forget.

No changes required. Comes with the correct GM connector. Just plug it in and start it up.

Of course, many wives-mine included, don't know the first thing about our gas mileage.

If I told her the "old" motor got 5 mpg and this "new" LS gets 30mpg, she'd say "well I guess that's better; good thing you did it..."




Now, to make sure I don't leave this page up in the kitchen...

From what I recall, the GM and TD5 potentiometers are very similiar, I don't see why with a little work, the GM couldn't be adapted to the TD5 pedal assembly itself.

Are you referring to the two track or three track Td5 pedal. I believe the two track (the one I have) is wired like the GM. Two potentiometers with different slopes. Both wired to produce positive voltage on actuation. (0-5vdc) The three track Td5 has one pot wired in reverse as a means of verification.

After all that, we need to see what the pedal response is like. It may still throw a code. We will have to see. Anyone have more info on this?

I think I found the GM mating connector at Mouser, 15326833
