There's a difference, my truck isn't obsolete. It does everything a new truck does, except better.

 

I installed a tbs on my truck about a month or so ago I haven't seen any difference but I didn't do a mpg test before and after either it might have helped but I didn't notice because my fan clutch went out around the same time so my mpgs aren't the best right now looking forward to a electric fan swap soon tho thank you for your input on that thread a while back as well

 

Never said obsolete, just no point of upgrading something that has the memory capacity of a GameBoy lol.

 

Now I'm not saying these things work, I'd have to know exactly whats programmed on it to know what its doing but that is not a resistor. It is a chip. Essentially its a processor that runs a set of functions. It is exactly what they advertise it is. These chips are the processors on our ecu. They hold the sets if instruction on what to do with inputs. This thing take the inputs or outputs and changes then based on its own programming to set timing and fuel trim to different specs. You can do the same thing by removing these chips from the ecu and flashing them however this way is much less invasive. On new cars you still do the same thing except the programming is easy to access but still you are just changing the fuel trim and timing.

 

Funny..... Yet not funny

 

Small change to your otherwise perfect statement.

 

wasn't meant to be funny he was wanting some ones experience with one so I gave him my 2 cents I had a buddy that installed one and he said it helped him a liitle bit but he drives a newer chevy so I guess different truck different results

 

Hyperchips or something like that from summit custom makes chips for the map ecms for obd1 vehicles you tell them what you've done to your motor they build a chip for you, But its like 400$

 

No problem on the e-fan swap info. Let me know how that turns out. Thanks for the info on the TBS as well. I think the problem with so many of our mods is, they're done in a very short period of time, thanks to this site, and it's hard to pin down a single gain. Except for the e-fan! That was the one single item that I was able to say WOW about.

 

I saw what these magic chips were all about several years back when it came up on one of the atv web sites. As soon as fuel injected atv's hit the market, they began to advertise them as gaining as much HP as the atv originally came with. The answer to hp and power curves was an aftermarket ECM. Hundreds of dollars for a few hp that actually works. Not pennies for a dream machine.
