Smarty Speed Limiter

[JonKing]

I set the limiter at 160 mph, but it cuts out at around 110 mph, has anybody had this problem? Thanks

Jon, You may be hitting the Rev limiter

 

[JonKing]

I'm not hitting the rev limiter because if I turn the speedometer off I can reach 128mph (gps). I'll try setting it again.



Thanks-Jon

how bad is it on a mostly stock motor to run it at the 4g limit with the smarty. good bad? or ok once in a while. any sug. thanks.

Bad idea IMO But to get the 4k program you have to meet the "requirements" to support the TnT/R program... ...

I think Jon meets the requirements.

I've not found a place to really open mine up yet... but at 100 mph, I'm just loping along at 2300 rpm! :-laf

I had mine to 105 Saturday and still had lots of RPM left

 

[JonKing]

I can hit 118 stock with the speedo turned off and 128 with the smarty letting it go to 3500rpm.

jonking went to a gear ratio calculator for my truck with g56(. 79 overdrive), 35inch tall tires and 3. 73 gears. at 3500 it was 124mph. did the same calculation for your truck with auto(. 69 overdrive, 35inch tires and 3. 73 gears came up with 142mph.

enafziger what special gear ratio do you have? 100mph? 2300rpms? LOL

enafziger what special gear ratio do you have? 100mph? 2300rpms? LOL

I have 3. 73 gears with a G56 transmission. I'm running 37" Toyos, and I just added a Mitchell overdrive unit, which gives an additional 18. 2% overdrive. With the OD engaged, it effectively turns a 3. 73 ration rear end into a 3. 07.

Thus,

2300 rpm = 104 mph
3200 rpm = 145 mph
4000 rpm = 180 + mph

Or, in more realistic terms, 75 mph is 1650 rpm, which equals better fuel mileage! Well, hopefully anyways. I just got the Mitchell unit installed, and I'll see what it does for mileage.

I don't anticipate I'll ever see how the truck handles at top speed anymore...

You have to meet the requirements? to get it. I think anyone can download that on their SMARTY. maybe to get full benefit from it you have to meet the requirements. But you can load that on a bone stock truck. am I correct Bob.

THE TNT/R race program is vin locked and only given out on special request.



and yes aftermarket valve springs are mandatory.

I'm running 37" Toyos,--Eric

your signature says 35x12. 50 toyos.



get back to us on the top speed when you get the nerve up..... LOL.

 

[ENafziger]

your signature says 35x12. 50 toyos.

Good catch... I've updated it on other sites, but I guess it's been awhile since I've done it here. Thanks!
