So I finally started to get some quality riding in (as well as getting the Autotune process going on the FP3) after my stage 1 upgrade. It's a Bassani RR and SE Ventilator. I commuted into work this morning and it definitely seems like I lost torque on the low end. When I had the stock setup and I jup off the line, that sh*t threw me back. Now not so much. I've flashed the ECM with a base map (V&H pro pipe, comp baffle, hi-flow A/C) and I flashed some autotune updates to it from some short rides over the weekend. Am I imagining this or is this a possible effect of the stage 1 upgrade?

 

It 'could' be imaginative... but I would get some more auto-tune maps done. I run a different tuner... so not sure, but can you see your timing/advance maps?

 

I'm a novice at this and don't plan to do anything more than Stage 1 so I am not sure the FP3 has that level of insight. I will check though.

 

Yes you can adjust timing through the FP3, it's a simple procedure but of course you need to know how much to adjust which goes beyond my pay grade!

I would keep doing some auto tunes and see. Remember also that during the auto tune sessions I believe the AFR's or some table is disabled which may alter the ride a bit until the values are learned and reflashed

 

Gotcha man. Thanks. I am gonna run auto tune for at least a few tanks of gas if not a few weeks.

 

not unusual at all. Different setups produce different outcomes. Some lower torque and increase HP (which is usually the case since the goal of a high flow system is to maximize HP).


If you already ran autotune, you can keep doing it, but I doubt you'll get much more out of your system unless your system sounds like it's running lean or backfiring.


You're next best bet is cams if you want to bring the torque back significantly or consider some baffles/inserts which can bring some (key word, some but not much) life back.

 

I have a nice cell phone mount I'll get on tonight so when I'm back out riding (probably Wednesday) I can get some live data as to what's happening. I'd like to see running temp as well.

 

I thought that RR exhaust was supposed to increase low end torque.

 

Unfortunately, this is common, but not because of exhaust selection. This is the outcome of these cool new diy "tuners". There's no exhaust combo out there that will feel worse than stock when properly tuned. A stage 1 and a good tune is night and day over stock at every rpm range.

 

I have a couple of observations. The FP3 while autotuning does not run the finished map. I don;t know exactly what it is running, but when you finalize the map it runs different than while autotuning.

You could try a different base map, I think the using the comp baffle map may be giving you too much fuel, try the regular baffle map.
