You would want to talk to the manufacturer and ask if it will work with direct injection, considering they run at higher voltage than a PFI injector.

So ive done about an hour of searching and can't seem to find proper information on the racerom traction control

How does it work? does it use fuel cut? spark cut? ect?

How does it modulate the fuel cut between the cylinders? Does it cycle through each cylinder 1 by 1 like racelogic does to preserve engine longevity? or does it cut fuel to the whole system for a split second?

How often (times per second) does racrom collect data from the front wheel speed and the rear wheel speed and how often does the system make adjustments?

Also how adjustable is the system? can you change what % of slip you want on the fly like you can with racelogic, so actual power output doesnt matter on any type of surface conditions?

The reason I bring this up is because on CARB legal tunes for supercharges, you can't use racerom to adjust these parameters because if you mess with any of the tuning, you no longer have a CARB approved tune on the car. With Raceogic you could retain the CARB tune and possibly have a far superior launch and traction control system than racerom can provide.

Thoughts?



The system does work with direct injection, I was just curious if anyone has tried this solution. If not then I can find someone who can install it and give the forum a proper review of the product.

The only reason why I'd think RL TC system maybe better is adjust-ability on the fly.. Where as in ecutek you would need to do a map switch or flash.. You would also save money and install time with the ecutek..

That still leaves many questions.

1 what about supercharged users, boost control is very limited as an option

2 how accurate is ecutek? how many times per second does it analyze data and respond to it? if it isnt more than a few hundred times per second than it isnt a viable option for me where as the RLTC can calculate and adjust every 1/1000th of a second and has its own computer manage the input/output of data and not relying on the ecu to handle everything, over stressing the system.

3 still doesnt have on the fly adaptability. from my understanding of the racerom traction control. It is a preset map that decreases boost/power and can't account for all road conditions. This is where RLTC would excel and you wouldnt need a new tune for traction control every time the climate changes from summer to snowy winters.

4 Consistency, Supra owners are all to fond of this struggle between power and traction. Boost by gear and ecu controlled traction control only goes so far. Some launches would be flawless where as other launches on the same day would either bog the engine or furiously spin the tires. Those who have utilized RLTC praise on how much better it is at keeping the tires from spinning when it is wet/dry/cold and the system maximized the traction regardless of type of tires, wear on the tires, or how the suspension was set up . Our cars also suffer from its light weight and even with larger tires and better suspension the car struggles to put the power down.

boost control is limited on superchargers because it's a mechanically driven supercharger. people have been trying to hack around the problem for years, some with more success than others. ecutek can control anything that'll accept a pwm signal, so once a good hardware solution is in place the software is already there to control it.

it calculates fast enough. as fast as the ecu in the car i suppose. this is another theoretical argument. i doubt you'd see much functional improvement in real life from increasing the sampling rate even 10 fold. it's not a 1:1 kinda thing. 10 times faster != 10 times better. there's a point of diminishing returns, which pretty much everything with a modern processor has surpassed as this point.

as for adaptability, that's completely up to the person setting up the system. you could absolutely set up comps based on ambient temp or whatever else, or even wire in a tire temperature sensor and use that if you felt the need.

how good the system works has everything to do with the person setting it up and calibrating it, and very little to do with the hardware it's implemented on, imho.

It blows you have to pay extra to get the carb cert and then go buy a better tune from someone like @DeliciousTuning, but this what you have to do if you want a carb cert and a better tune..
