I've never seen or heard of this before, it dosent look like it would do much tho, There usually aren't many parts on ebay worth buying for f-bodies except for rims/tires.

 

I don't really know if it would help but the knurled nuts sure are pretty. I think the PCM should know when the throttle is "really closed" And not be fooled into thinking it is where it is not. It might make it think it was at WOT sooner and dump more fuel which could lead to rich condition and power loss. I guess I could be wrong, so, I'll wait for other opinions.

 

I wouldn't spend my money on it. Looks like a slightly more expensive cheap trick to rip off people. Stock TPS is perfectly fine and does not need any adjustment.

 

Well it won't make the car faster in the 1/4 but it probably will make the part throttle crisper. I have the infamous $90.00 TPS Enhancer that some people liked to flame. It's got a fixed full advance and fuel at 70% throttle position.I like it and if I take it out it now feels like something is missing. This probably does the same thing but is adjustable.

 

Hey Ion, I've got OBDII LT-1 Edit which I haven't locked to a PCM yet. I've also got an extra ODDII PCM. I'm planning in the spring on putting in FLP Longtubes with the dual cat ypipe, 1.6 rockers and a 58mm TB.
Can you write me a tune when the time comes and email it to me that I can flash onto one of my PCMs or would it be better to get one from you then make a file out of it for further tweaking.

I'm new to this but a quick study. Writing my own program from scratch may be more than I can achieve at this time but I could start with the HPP3 program as a base for instance. Getting a program from you probably would be the prudent thing.

Thanks Dan

 

Hmmm why would anyone flame the TPS enhancer?

 

Hey Heatmaker did you buy that IAT Module for $5.00 on EBay?

 

That shouldn't help at all on our cars from what I have learned. On 3rd gen F-Bods, yes, but 4th gen F-Bods have an auto re-zeroing or so to speak TPS. That is why ours isn't adjustable So long as it is about .2 to .9 volts with the blades closed, the PCM will/should see proper 0 to 100% throttle position percent. Any adjustment lower or higher will cause SES lights. So, the only adjustment needed on our cars is to ensure it is between .2 and .9 and the PCM handles the rest and should treat all values inbetween .2 and .9 the same. Adjusting it outside this like I said is no good and gives an SES light. So, why buy a gizmo that adjusts the TPS when no adjustment is necessary so long as you are within a certain band??? I know... you would buy this gizmo for $35 only if your TPS is bad and a stocker costs like $50

 

No...brought a crapatelli instead.

 

touche!
Ya I got that thing when I was young.

 

Just curious.... if you think it's crap, and my opinion is just about the same as yours, why did you buy it??

I can think of so many other things you could buy with that money that will yield much more HP (actually, if you think about it, any HP increase compared to that MAF's zero or what I like to call "negligeable", would be noticeable)....

 

When I first got the car it had a mysterious problem where it would die inexplicably then restart and be ok for 20-80 miles. Turned out the waterpump was leaking onto the opti and the computer was bad and would spit out a dozen codes one of which was PCM Memory. After replacing the PCM opti and waterpump everything was fine.
I agree the granatelli is a waste of money.

 

That looks like a $20 aftermarket TPS with the slotted screw holes. I wouldn't pay that much since the only "extra" stuff you're getting is the new harness plug and a couple of nifty red screws.

 

Well that's no good, the stock programming does that by 66%
