i'm new here and going to get a tc soon. (2 motnhs tops)

looking at parts i dont see any remapped ecu's or chips out for the tc. but i do understand that the when purchasing the trd supercharger they remap the ecu for you and increase the max rpms correct?

so would it be more of a deal with getting ahold of the dealer tool and reprogramming it to work for an na application on 91 octane to get a couple more ponies on top of that?

also for piggyback units whats a good one to go with? that wont kill my engine. and do they remove the top speed limiter and rev limiter also?

 

i dont have a s/c but im pretty sure they dont increase your max rpm. Toyotas are not high reving engines if you wanted that get a honda they need to rev high to make their little power. as for remaping the ecu for n/a i dont think its that easy

 

there are no actually ECU upgrades for tCs,
as for the TRD s/c reflash, you are getting bigger injectors, which means more fuel. you need to basically RESET or TEACH the ECU to read correct info and dump the right amount of fuel, etc.

that reflash will do nothing for your n/a tC
and no, it does not increase the revs

 

Unichip should free up a few HP on a n/a tC. I believe it allows you to bump up the rev limiter as well.

 

for the money, i dont rec. Unichip

 

well emanage ultimate can raise rev limiter too... lol

 

and its cheaper

 

and cheaper to tune


screw the unichip

 

yup
and yup

 

Does the PnP harness work for emanage ultimate?

 

yea, ZPI has PnP harness for ultimate

 

A little breakdown, both are still expensive.

Emanage -$300ish
PnP Harness - $300
Dyno Time - $150hr
-------------------------
Unichip w/PnP harness with a base tune. $800ish
Dyno Time -$150hr

 

wow thanks guys i guess i'll go emanage then, and see what i can do from there.

i want to free up the rev limiter so i can hit higher top speeds at the salt flats when i go with my old car club once in awhile.

 

dont expect to go to mutch faster the tc sucks ***** up top

 

its a little harder to find a unichip tuner atleast out here and they charge about 100 an hour to tune a emanage at alot of shops out here

 

Yea I was just giving my quotes I was given. Im sure I can find cheaper emanage tuning, but unichip tuning is $150hr all the shops around me.

 

raising the rev limiter is pointless on an otherwise stock motor. The poor flow of the stock head, the cams and the huge stroke will not allow you to make more power. If you look at the dyno graphs, you can see the power already dropping off towards the redline. The power will just drop further beyond the stock rpm limit. Also the piston velocity would be really high from the 96mm(I think) stroke. Just get it tuned to the factory rev limit and leave it be, unless you get some major engine work done.

 

oh, and toyota has made some good high reving engines (2zzge, and the good for its time 4age). Our engine is just not one of them

 

umm your "revvs" have nothing to do with that, its the gearing, and the speed limiter. your not geared to go much faster than the 127 were ALL limited to. if someone said they went 130-135(which have been said), there lying

 

this is tru
freein your Revs isn't going to give you higher top speeds
