has anyone seen a power programmer for an 07 tacoma? i just put a six inch lift on my truck with 35's and my fuel economy went to hell and its not shifting very well any more. i havent been able to find any kind of programmer or chip.

Never heard of one, the closest I've seen is the URD MAF reprogrammer. If you're running 35's shouldn't you be thinking about a regear instead of a programmer?

i was thinking more of adjusting my speedometer, changing the shifts and getting some more horsepower out of it. i dont plan on doing any hard core off roading with it.

JET Labs makes an ECU upgrade but the people who have gotten it say it's crap. Plus you have to send your entire ECU to them, making your truck useless for about a week and a half. You can't really do anything about the transmission as it has it's own separate control unit and adaptive shifting. Try unplugging your battery for about 20 minutes and it will reset everything and relearn your driving habits with the bigger tires. It should help.

changing the gears will help with all of those except the speedo. Gears is just not for offroading, but it helps bring the powerband back after the larger tires.

Wow do people that mod like that really worry about gas mileage? Gotta pay to play as they say.

Shifting problem sucks though... try resetting the ECU as suggested earlier and let it relearn.

Actually, regearing can get the speedo to be more accurate.
In my 82 Toy when I was running 35's, I regeared with 5.29's and my speedo was dead on.

What about those devices I've seen for Ford and Chevy trucks called Edge programmers to adjust power. I saw an episode of "Trucks" where they used one to get more HP out of the truck, all with the push of a button. Yeah, right....:)

^^^ Those work and are proven to work but no one makes them for Imports they are for Domestic Vehicles for the most part. I don't know why almost no one makes them for Imports...most likely something to do with the ECU. They are very popular and effective on diesel vehicles!

It would be harder to make a programmer for import vehicles because so much of the power comes from computer tweaking already. It would be more expensive and less effective. Domestic gas engines are less complicated, so computer upgrades can be more effective, and diesel engines are the least complicated, so chips can be very effective.

You do run risks with a chip, though. You have to keep an eye on engine temps, you probably want to go with synthetic oil and change it more frequently, and when you're getting more power, you're losing fuel economy. As someone said above, you have to pay to play.

With a 6" lift and 35"s you have to re-gear if you ever want your mileage/power back.
You will not get your previous mileage back, even with re-gearing. It just takes more to spin these wheels.

Im pretty sure diesel engines are far from the least complicated. The reason you can make power from them is because modern diesels have a turbo. So you can tell it to make more boost:eek:

"chipping" a natural aspirated engine will net next to nothing as far as HP gains(dont confuse what im saying with proper mods and proper dyno tuning with a wide band either)

Now if it has a turbo... Thats a different story.

Just a thought - are you sure they did not change the speedo gear when it was regeared? That is what they did to my kid's 93 Toy truck when when he had it regeared. The older models use a mechanical drive (cable from the tranny) and our newer trucks use a sensor that counts the revolutions to determine speed (hence why you can adjust the tire size in Scangauge and get an accurate read).

Unless it's a VGT (Variable Geometry Turbocharger, Which is quite possible especially on diesels) you can't just tell a turbo to create more boost. Even with a VGT it only goes to a certain point. Turbo's create more boost with higher engine RPM because they are propelled by exhaust gases exiting the engine and they aren't computer controlled (Except for VGT's) so you can't just tell them to SPIN FASTER!!! The only exception to this is when a wastegate is involved but usually when you have your foot all the way on the gas the waste gate is totally closed therefore creating the maximum amount of boost possible. The only way to really get more boost is by getting a bigger Turbo.

Diesels are by far the simplest type of Internal Combustion Engine. They have no spark plugs, no distributor, no ignition system. The only thing you need for a Diesel Engine to work is pretty much just a Block, Piston, Crankshaft, Valves and a Fuel System. Diesels work by compressing the air/fuel mixture instead of igniting the air/fuel mixture with a spark from a spark plug. This is why Diesel engines have compression ratio's of 16:1 to 25:1 and also why they are more efficient then Gasoline engines. As a result of the higher compression ratio they have a much longer piston stroke and therefore can produce MORE torque with LESS fuel.

The main reason diesels have turbo's is to reduce sooty emissions by forcing more air into the chamber, this increases compression, increases scavenging (i.e. getting the exhaust fumes out of the cylinder quicker allowing more clean air to come in) and puts more oxygen into the cylinder which helps burn the fuel more completely and cleanly while also producing more power. Thats why when you see an older diesel with a turbo mash the gas, you see all that black smoke come out, that is unburnt fuel that is wasted because the turbo is slow to spool up and create boost. Newer diesels prevent this with computerized fuel management systems which older diesels don't have. Because of the diesels simplicity and efficiency diesels can get the same amount of power out of an average of about 40% less fuel vs. a gasoline engine.
