Function wise I did not think much of it when i tested it.... felt it was too restrictive regardless of parameter settings, also big drawback was not having on the fly adjustment with the way they had it set up (needed to stop car and hook up lap top to change settings).

Have used it on piston engined cars and found it not as good as my RL unit.

Was this using the version 3 software or 2? I have not looked at the traction control settings yet, but overall there is more control everywhere with v.3, so hopefully they have improved the TC... I'm using an M400 as well.

SPO, racelogic.co.uk for estimates on prices. . . ~$1500 with all the bells and whistles, supposing your wheel speed sensors are in tact.
Haven't looked for any dealers stateside yet. . .perhaps if enough interest is generated, we could try and get a group buy going. . .I kind of doubt it though. . .people still seem a little too weary of it all. Please post back if you find any good deals and I'll do the same.
RICE, thanks a million for your help, once again, providing some invaluable insight. I'll probably be PMing or posting for your help some more once I actually get it installed.

"here is an idea, read the ******* thread !"
I just stripped my own engine and after very heavy traction control use not one piece in the engine is damaged or badly worn, so I can catagoricaly say that it (race logic with my programing) has no ill effects at all to engine operation or life.
I made sure I personlay tested it before i put in my new set up
and as a side note my levels of knock posted were influenced by a broken left hand engine mount (the alloy one).100% fantastic product, go buy it

rice, i did read the thread. i guess what i intended to ask was why it was okay to run the rotors super lean at times? rather than it worked fine and everything's fine after extensive use.
if it's 100% cut, i can understand it as there would be no combustion anyway... but at partial fuel cut, i suspect it to run super lean. when i see anything above 15 AFR under boost, i wouldn't hit boost again until i knew what was going on. just asking; that's all.

), hence there are no issues You need to remember this is not a hit and miss situation, its finely controled down to cutting individual injector cycles and alternating rotor faces and rotors, its very advanced and is proven way to do things from F1 engines to our shitty rotaries
What you see on your AFR instrument is an AVERAGE not what is happening on each firing event
so one will be dead lean the other very rich (normal) the average you will see on your meter is all of these combined which will obviously show leaner, but its is not what is happening down on a micro level, cycle by cycle.

But all of the brains and logic behind it is in the above posts 100% (already shared for free) if you want to apply it yourself

* & with digital adjuster you can set percentage of slip in 1% increments on the go, which is realy handy for when the track conditions change.
* also launch control is activated by the same adjuster button
Its not some gay 2 step BS either! LOL. Its a proper pre set up parameter that gives you more wheel slip to X speed before the normal level of straight line traction control level engages = F1 quality starts.I cant say how happy i am with owning/using one of these...... i dont get paid by racelogic to say this, but its honestly the single best mod i have done to any car period.

I was curious to know how the RL would work with nitrous cars... wet system of course..
btw, I may be up to join a group buy on this providing the price is good.

It won't work with Nitrous. Think about it. What happens when you cut fuel and have Nitrous squirting into the intake tract? Unless you get fancy with some relays.

I'm sure I can arrange a GB w/ RaceLogic if there's enough interest... There was a GB w/ them a few years back, but I don't think anyone in on that GB ever came back and posted their results lol.
If there is interest in a GB, feel free to start a GB thread in my vendor subforum.
Thanks

Speaking of which, I'm gonna be running a GB on 'em...here's the thread: https://www.rx7club.com/fdnewbie-imports-172/gb-racelogic-674843/

For convenience sake, when programming the cut tables, wouldn't it make more sense to group the injectors by rotor and connect them to the RL this way:
1 = Front Primary
2 = Front Secondary
3 = Rear Primary
4 = Rear Secondary
Then you have rotor banks (1,2 and 3,4) to select the cut from. One thing I don't get is Rice's four sequences when there appears to only be three in the RL manual. Using * for combustion and X for misfire and the RL cycle of 20 per RL manual:
Normal Operation:
---- ---- ---- ---- ----
1234 1234 1234 1234 1234
**** **** **** **** ****
Cut Sequence #1 (2 out of 10 per Rice's suggestion):
--RR ---- ---- FF-- ----
1234 1234 1234 1234 1234
**XX **** **** XX** ****
Sequence #2 (4 out of 10 per Rice's suggestion):
--RR ---- FF-- --RR FF--
1234 1234 1234 1234 1234
**XX **** XX** **XX XX**
Sequence #3 (5 out of 10 per Rice's suggestion):
--RR FF-- FFRR ---- FF--
1234 1234 1234 1234 1234
**XX XX** XXXX **** XX**
Sequence #4 (7 out of 10 per Rice's suggestion):
--RR FF-- FFRR FF-- FFRR
1234 1234 1234 1234 1234
**XX XX** XXXX XX** XXXX
Hard Cut:
FFRR FFRR FFRR FFRR FFRR
1234 1234 1234 1234 1234
XXXX XXXX XXXX XXXX XXXX
Doing this for the three rotor would be very similar, just wouldn't fit in the sequence of 20 quite as well:
FFMMRR FFMMRR FFMMRR FF
123456 123456 123456 12
I guess you could just leave that last one to fire every time and then do the progressive cut over the first three sequences. No easy way to get even numbers but 3/9 and 6/9 so I suppose you'd have to have some uneven distribution of the cuts...

2 = Front Secondary

Resurecting an old thread. I'm thinking about getting the RLTC. I looked through the manual and had the same questions as many people in this thread. In general, I understood the cut table programming to work similar to what rxcited2 describes above.
Can anyone confirm that his programming above is correct?
