Long story short I purchased a dirt track car
I'm getting everything ready to race

It's a jdm b16a w Gsr cams
Type r retainers and springs freshly rebuilt
Was tuned and dyno'ed by Darius in monroe
It doesn't have a tach
The guy told me he had it dyno tuned chipped the ecu
With a two step

So here's the deal
What exactly is a two step ?
I drove it around warmed it up good
Then decided to turn er loose
I notice that if I accelerate slowly it does good
But if I go full throttle it seems to go to what sounds
Like 4000-5000 (sounds like)and rev limits
Forcing me to shift super early

Any ideas ?
There isn't a cluster so not sure about checking
For a cel or pulling one

I just drove it a little more
There is a district rev limit very early

Might have to take it to my tuner
It won't lemme go past 4.5. - 5k ish

 

What would be the stock ecu to use
It's got obd2 injectors

 

Found the speed sensor broken in half ,
Could this be the problem?

Thats your problem. 2step engages below a certain mph to make sure it doesnt engage while driving. No speedo cable, ecu think car is stopped amd emgages the 2 step
