AEM - Traction Control

Recommended Posts

Not technical but has the potential to be if someone clever comes along :)

 

I know a few of you use AEM ECUs - do you also use their traction control and if not why not?

 

What does RLTC offer that AEM don't?

 

(I'll wade through the AEM forums for info as well but thought I'd ask here as well)

RLTC is based on ABS signals

AEM TC is based on the engine load/rpm's/acceleration rate.

 

The RLTC is superior...as it can take corners into account...having all four wheels monitored is better than monitoring the engine!!

So would the AEM setup be better or worse than my standard UK setup (with the 'amazing' G-Sensors etc)?

 

I don't feel that I need RLTC at this moment in time but expect that to change when the twins go on, however I don't want to waste money at this stage if the standalone I opt for (at this point undecided) is capable of getting close to RLTC levels.

Because it's bloody difficult to set-up, and nobody has managed to write an easy to understand "how to" on how to get the best out of it.

AEM TC is shite. It relies on a set possible engine acceleration. If this value is exceeded, it presumes it is wheelspin and cuts power. I am sure I don't need to explain why that is s***.

 

RLTC all the way. (Unless you plan Motec or Autotronic, and only maybe, even then).

Well at the moment I'm favouring Motec with AEM second - I was just curious to see if anyone had used the TC because I know of a few people with AEM and RLTC.

It's not really fair to say it's shite. The same system seems to hold them F1 boys on the track at the weekends allright.

 

It's not as good as RLTC agreed, but compared to the stock system it can be mapped to be lightyears ahead.

No allowance for corners, wet weather, different surfaces (and hence different friction coefficients).

 

Yeah, setup on a specific track for set conditions, its fine. On a road car, no. The situations from first class motor racing and road cars are so different as to not even be worth comparing. Carefully controlled conditions vs the complete opposite.

Nearlly right. In the same way as you can set the RLTC for different weather conditions you can do the same with the AEM. I believe that's what the TC Sensitivity RPM input is for. You can rig a switch up so that you can switch between different sensitivity values and hence have an allowance for different weather/surface conditions.

 

The point is about the F1 cars is if it will hold them around a corner, as a method of controlling TC it's not as bad as some people will have you know.

So what you are saying is that the AEM has the potential to offer fairly good TC but very few people know how to set it up.... considering I'm fairly happy with the standard setup I suspect it would be an upgrade then.... but of no use at all if nobody can make it work...
