Racelogic Config File request

[Guest Mike 93MKIV]

I'm in the US and was one of the early US Supra owners of the RLTC when I had it fitted in June '02 (adjustable slip and launch control). My purchase decision was based largely on the information I read here. For that, my thanks. The Racelogic is one of my favorite modifications.

 

From browsing the forum here, it appears that some members have put some effort into tuning the RLTC for the Supra and I was hoping one or more might share their set up with me. I've set up an e mail account for this at [email protected]. I'd also be happy to reply to any PMs or messages to that address with my main e mail address but would prefer not posting it here to avoid spam, hence the "disposable" address.

 

Some info on my setup. I have a US spec auto Supra with a single turbo, 750 cc injectors, FMIC, 3200 stall torque converter, etc. It dynoed 608 SAE rwhp @ 26 psi with the converter locked. I'm running an SP63 turbo which spools a little faster than the stock twins in "true twin mode" (non-sequential) so the power hits slightly sooner than the #2 turbo in normal sequential mode. The car is not a daily driver and I normally run 22-24 psi on 100% unleaded race gas (99 MON).

 

Quite a few US Supra owners have purchased RLTC units in a couple of group buys and one has asked for assistance with setting his up. When I got mine, someone was kind enough to send me a copy of Graham's application and a data file that I was told was what most UK BPU Supras were running. It works pretty well on my setup although it could defintely use some improvement to handle my higher power level. My current settings tend to allow too much wheel spin to build at lower speeds (

 

I've also never gotten around to setting up the launch control properly since I don't drag race the car. The fellow owner who has asked for help getting his unit initially loaded is running a T78 on a 6 spd. I'd suspect he has about 650 SAE rwhp at high boost and is rather interested in getting the launch control set up.

 

Sorry for the long post. Any assistance would be VERY appreciated. BTW, I've made quite a few trips to the UK in my past when I worked for Tadpole who were based in Cambridge. I have very fond memories of driving in the UK although I gather that the speed enforcement has become a lot tougher since my last visits there about 6-7 years ago. I hope the beer hasn't changed though!

Hi Mike - nice to hear from you!

 

I have taken the liberty of asking the chap who makes these at Racelogic to give you a email direct about the recommendations - his name is Ben

 

Phil (Terminator on this BBS) has loads of experience with the set-up on these - and I suspect that his DAT files are up to speed - or if not he can probably advise

 

Would love to check out more about your set-up

 

PS Beer is still good - in parts!

launch control is easy to set up, its just a case of finding a good rpm to launch at. whats also worth looking at is the full throttle shift option. this is not wired as it comes from the factory so needs a bit of wiring to the rltc ecu and the clutch switch. again easy to setup, its just a rev limit on clutch down.

 

i dont know of any single supras with a tuned RLTC, but im sure there's someone somewhere.

Welcome Mike.

 

Beer is great, but cameras seem to breed over night. The government has found a new way to raise tax.

 

You have a PM.

[Guest Mike 93MKIV]

Thanks Paul. Not the Paul W I acquired mine from?

I appreciate you forwarding my contact info to RL but I suspect I'm beyond the basics. I't would be great to have a specific contact at RL though for specific questions. I promise I won't bother him with trivial issues. You might mention that I was one of the first 3 or 4 US Supra RLTC owners and a big advocate of it in the states.

 

I'd appreciate it if you could PM me his e mail. Phil has already PM'd me and I've replied in an e mail using the forum. I'm hoping to have him take a look at my config and make suggestions.

 

Thanks,

Mike

I have a slush box :-) which I think requires a different launch control strategy. I suspect I should set the rev limiters well above my stall but low enough to limt massive wheelspin early on and transition to normal TC mode as early as possible without bogging. On an auto with a stall, I suspect you still have to balance the throttle and brakes by yourself to make use of the LC.

 

Full throttle shift with a raised rev limiter works fine on my car without the RL (auto...) although I actually use the rev limits. I have a modified redline (8000) but use the RL soft/hard cuts at 7400/7500 with stock cams/springs in case I do something really stupid like forgetting whether I down shifted 2nd before a pull. Thankfully, hasn't happened yet.

 

The other owner has a 6 spd and I've mentioned the full throttle shift could probably be enabled although I'm not sure he "purchased" it. My understanding is that it requires a switch to detect when the clutch is initially pushed and the US factory switch only activates when the clutch (starter interlock) is fully depressed. Is that correct?

 

There are a number of US single turbo Supras in the recent group buys. Hopefully there will be more RL configs suited for singles available in a bit.

I replied to the PM with an e mail. Your help would be greatly appreciated. I'd like to keep as much of the tread on my brand new BFG KDs as possible while tweaking things although I realize optimum acceleration requires slip and very accelerated wear.

 

I have fond memories of the beer. We can actually get a fairly good Newcastle and a few others here. Sorry to hear about the cameras. I assume they use radar and detectors are illegal? We have some odd quirks here which has made it hard for states to ban radar detectors (Federal Communications Commission regulates air waves and not legislature, radar (RF) jammers are VERY illegal) and even harder to ban laser detectors and jammers (governed as health issue by the Federal Drug Administation). ... Blinder laser jammer and Valentine One radar detector on my Supra. That said, I'm very careful and have more years without an at fault accident than I care to admit.

I just realized I can attach a file although there are limits on the file types. The attached file has a .txt extension to get around this limitation but is actually the dat file from Graham's application. I think it should be possible to right click on it and use "Save target as" to download the file and load it into Graham's app.

 

I'm using the FTS shift rev limits as full time limits as I have an auto with a G-Force ECU (8000 rev limit) but am still running stock cams/springs. The launch control settings reflect some changes I've made but haven't tested.

 

The fellow Supra owner I'm helping is getting his unit installed Friday. Since he lives in another city and doesn't have a notebook, Friday is the only chance I'll have to load his system.

 

Any comments or actual config files would be appreciated. Files can be mailed to [email protected]. I set up the address for this purpose and to avoid possible spam to my main address from posting it on a public forum.

 

One minor thing I've noticed in the config file is that each cut sequence starts with an injector firing while Racelogic advise starting with an injector cut to improve the response time of the system.

 

Thanks,

Mike

launch control, when enabled, initiates a different slip calculation and gives u a definable rev limit. on a manual it allows u to floor the accel on the line and just concentrate on the clutch. defining the launch settings is the tricky part and varies from car to car, ive still not managed to set mine up perfectly yet. my new local industrial estate has some excellent tyre paintings.

 

i would have thought u would set the limiter to below yr stall.

it comes with the unit, just not wired. u have to get a pin and wire it into the RL connector (the pin is listed in the manual). u then wire that to a clutch switch. on my jspec the clutch switch is activated when the clutch is pressed a couple of inch. im not sure of the us spec, i know u have the clutch down to start "safety feature", so yr probably right.

If the system is allowing too much wheelspin and then cutting power aggressively it probably means that the cuts are coming in too late.

 

If you look at the 'Slip control' tab in the software level 1,2 and 3 cuts have a corresponding 'assert at' value, this is the amount of wheelspin that is allowed before the cut is applied.

 

These are set as standard to 5, 10 and 15%, I would try lowering these values.

 

You will always get more aggressive cuts at lower speeds, at such speeds the difference in percentage terms of the slipping and reference wheels is huge.

 

 

Hope this helps:thumbs:

I initially thought the launch control rev limit should be set just below the stall to allow you to floor the car while power braking it. Although I haven't fully confirmed it yet, I suspect setting it higher would help the launch.

 

If it's set below the stall, as the car begins to move, the launch control rev limit will stop the revs from increasing and building boost resulting in it bogging. I think allowing the revs to increase 1-2k after launch will introduce some wheel spin (that the RL can largely control) but allow the engine to start building more boost to prevent bogging.

 

The RL units sold here without FTS evidently are also missing the harness wire and the US distributor jumped on the Yahoo mailing list to say you had to buy FTS to use it. That said, it appears all the RL units in the past have had FTS capability as you say. I suspect they still haven't changed things.

 

Paul,

 

My slip control values are at 3%, 8%, 13% per the BPU file I initially received. I have noticed some interesting things though when reading my current settings with a version of Racelogic's software.

 

The time threshold in the slip control "integral" settings shows up as .4 sec in Graham's app and .04 in the Racelogic SW. If it should be expressed in units of .01 sec, my current value of .04 sec may be causing the RL to use the integral cut before the less severe levels have a chance to control wheel spin. Comparing the launch control "start delay" fields, however, shows my start delay of 2 in Graham's app translating to .2 sec in Racelogic's software. The speed values that I've looked at seem to consistently show a value of 100 in Graham's app translating to 1.00 km/h in the Racelogic app.

 

Hopefully Phil will have a chance to check in here and provide some information. The fellow owner had to delay his install until next week but my car may be going down on Friday to have the torque converter pulled. I have a 3000-3200 stall 3-disc Precision Industries converter that easily allowed me to build 1 bar powerbraking with my prior SP57 but only yields a few psi with the .68 SP63. The converter came with a 2 year warranty with one free stall change and the warranty is ending. I'm going to the next higher stall and they seem to be good about going through the converter and refreshing things if needed as part of the stall change under warranty. I've been told by a number of folks that the drivabilty difference etween the two stalls is fairly small since the stall difference only full shows up under WOT.

 

My thanks to everyone for their input. I'd still love to get a look at anyone's files who is willing to send them.

 

Mike
