Any new feedback on Race Logic traction control for the FD
 

Hey

I am starting to consider the Race Logic traction control now that i believe i am convinced that it won't hurt my motor. I was just wondering if anybody has an new customer feedback that they may want to share for us.

Does anybody have any input on whether it helped or hurt your 1/4 mile ETs. I am running a Bfg drag radial, has anyone tried the unit out with a drag radial, and how much did it help you.

Any and all new input on the TC system is appreciated.

Adam

Is anybody using this?

Jim Swantko has it on his ~800 RWHP Supra, and there are a couple on RX-7s (Rice Racing, for example), but for the most part, I think that most of the units sold in the group buy are just sitting in people's closets/garages.

I've yet to see someone post installation pictures.

lol,

How much exactly did people end up getting the TC unit for with the launch control and no lift to shift option in the group buy?

Well, if people are willing to sell, let me know, i may be interested. must have launch control and no lift to shift option.

I would think BFG drag radials would be all the traction control you would need! ;)

I wish. I either launch too soft and bog, or i launch hard and spin in place. There is like no middle ground. One time it will launch beautifully at a certain rpm, and the next it wont launch at all and bog. Plus, i do a lot of street racing and am very rarely at the track. During night time condition, the ground tends to be cold and the tire just doesnt want to bite. Plus i dont like to lower the tire pressure in my tire to any lower than the 20 psi i have in them during normal driving.

adam

bump, sorry, but im really interested in knowing. Im sure someone has something to say about it.

1. They make portable rechargeable compressors.
2. You drive around with 20 psi of pressure in your tires on a regular basis?!?!

Their are several threads on Supra forums that will in part answer your questions. When programed correctly, they will improve all the things you mentioned. I said programmed, because you need to select when, and to what degree the cut occurs. Set it wrong, and it hits too hard, or at an in-opportune rpm, set it right, and you will really like it. I am one of the guilty RLTC un-installed owners, mine is probably destined for my Supra, and luckily is programed for road racing, so I will not have to fiddle to much. As an aside, does Jim know he's making 800??? I think his car is up there, but not 800. Carl

His signature says 785 RWHP. Close enough. :)

This was with the car as it sat. No iced intake - no reset ECU - no super lean A/F (11.3 or so) still had air filter, etc... no tricks. Also it was after about 20 pulls - so the motor was warm and it was in the middle of July in MD. Nasty dyno weather to say the least. I'm sure I could play and crack into the low 800's pretty easily - but that's not me. I want to know what my car does day in and day out.

Regardless - it's still plenty for me. :)

Without the racelogic it would be "almost" undriveable on high boost... pump gas it made 592rw BTW.

If you have questions about the install I'd be happy to help. It took me a weekend to install - nothing bad - but the harness is a bit tedious.

Jesus christ. now that's power.
Good job. That thing must pull unbelievably hard.

Nice Jim, I did not realize you had gotten that far, great job. What turbo are you running now? Carl

Nice numbers, does it have any track times to back it up? :D

Thanks... the car is lots of fun. :)

No times... but I'm sure they'd be pretty shitty as I haven't been down the 1/4 mile in about 3 years. haha

Carl... this is a 76GTS/ .81 A/R around 28.5 psi or so... not too bad for a VPC car.

I have one....installed....no time to program....shit!

But, it works. Engine is still good, so no worries there. Oh, mine is 'older version' of the racelogic...no pretty traction switch. Anyway, can't give much feedback, but I feel 'safer' now that I know I can limit my tail out habit.

How do you have this unit programmed? who would be a good person to do this?

It comes pre-programmed which I'm still using. You can fine tune it... but the standard program is quite good.

Anyone else install it yet on their 7? Just curious

someone was selling one on ebay, contact him, perhaps he has some info for you. he said he used it for 6 months - impressive.

yeah, I was following that listing. I might send him an e-mail and ask, although I hope he doesn't just try to "sell" me on it.

Tim

One forum member "Spank" uses it on his autox 7.

I'm the guy and I promise I won't sell you on it... I bought this thing to use at the track (roadcourse) and felt like I was cheating when I used it - so I didn't. I don't drag race so I didn't ever use the traction control. It was very impressive around the street but I say that for safety reasons only (keeps the tail in shape). Acceleration from a stop is probably improved because it won't let you spin your wheels too much, but I never timed a thing.

It was relatively easy to install (1-2 hours).

Mark,

what settings were you using when you went to the track (road course)?

Tim

Racelogic
 

It's awesome, wish I would have gotten it along time ago. A few things though.

The directions where slightly incorrect when connecting to the ABS connector, if you have a shop manual just verify what they are telling you is correct. It was pretty easy install compared to like the water injection kit. I mounted the controller behind the ECU. It has good diagnostics with the little green led when getting the thing up and running you can tell if any wheel is not being monitored. Took about half a day to install and figure out that their directions where not correct.

Not great for autocrossing other than the launch, the low speed tight turns give it a fit, but that can be programmed out to some degree.

I had it on when I went to VIR a couple years ago and it was fun standing on it out of some of the slower low gear turns and being able to hold down the throttle through the long sweeper on the back of the course. I was on street tires though (BFG KDs).

It's great fun to stand on it in 1st and 2nd and 3rd geer and not spin the tires like crazy. It works just as well in the rain...except brakes don't :-). It's as good as they say it is. I haven't quite got the full traction launch mode working as well but my clutch is not in great shape.

However, you can still upset the car enough with a sudden surge of boost in a turn and loose control but you shouldn't do that anyways.

My car traps about 119 in the 1/4 @ 11-12lbs of boost to give you idea of my hp.





I wired the clutch switch for the full power shift, that works awesome.

Tim,

I didn't use it long enough to use the "right" setting. I know that the 10% was a little restrictive (it came on sooner than I wanted), so I would have probably settled on 20% if I had stayed with it. I suspect that you would change the setting depending on the track. At the end of the day, I figure that it is a great system for a very good driver (which I am not) who knows the limits of the car and can use it to its fullest, or a new driver (which I am not) who is afraid of making a mistake, but may never be a good driver by using it.

finally we are actually getting some real life reviews of the product. I cant wait for someone to start talking about the launch option and how much they love/hate it, or how much it helped/hurt them.
adam

Any other update ?

:-) neil

wow, back from the dead. lol

used it this weekend for the 1st time for autox...was raining pretty bad so i used the wet setting. i am running ECSTA V710 285/30-18 w/ 425rwhp and experienced no wheel spin. I prolly cudda run 10% but was too nervous about wiping out.

anyhoo, i didnt even noticed traction kicking in but the course workers all came up and asked about it cuz the car sounded like an F1's traction. so i guess it's a thumbs up for me. i'll need to try more slip so see how it dials back when actually having some wheelspin.
