J Series swapped Mazda Miata. Tuned on Haltech.
J35a4 engine. Stock Miata transmission.

We cut the tuning short due to a battery voltage issue and high fuel injector duty cycle. Nonetheless it still did great.

I mentioned using a Haynes Repair Manual to a customer the other day. They never heard of such. There is a whole generation of car enthusiasts out there that know nothing about these books.

2001 Honda Accord. F23a engine.

Red dyno graphs = Stock engine computer.
Blue dyno graphs = Chipped ECU tuned on HTS.

Not huge gains over the factory ECU 🤷

Boosted B Series. It lays over and misfires around 6800 rpm's.

How many gas stations did you pass on the way here? Expecting your mechanic to go and get your fuel is crazy 😵‍💫

Acura Integra (dirt track car).
H22 swapped.

It came in for some help. It was low on power. I found that Vtec was not working. Whoever added the Vtec to the chipped computer failed. All is cured now 👍.

Before & After dyno graphs pictured.
2nd gear dyno pulls are pictured. I could only find 1st, 2nd, and 5th gears. This is the second car in one week with this issue 😒

2000 Lexus IS300.
Stock engine with a CD09 transmission swap.
The vehicle was tuned on a LinkECU.

On zero psi 😂.... The factory NA 2jz made 194 wheel horsepower and 193 wheel torque.

I believe this is my 1st time tuning a stock NA 2jz 🤷

1994 Mazda Miata (turbocharged).
We installed a Clutch Masters clutch. We replaced the brakes on all 4 corners. We also replaced the parking brake cables. The car is now being dyno tuned on Megasquirt before going back home.
