So, I've been banned at 124spider.org for just trying to create a summary thread for ECU tunes I know of. The worst thing is I lost my notes from that post I created, but anyways will try to recreate it here.
The backstory is I'm lost with all the options of the ECU tunes available and really looking for a piece of advice. My goals are city driving with regular time attack events and track days. Fuel is always 98 octane (aka 93 US). No performance mods (except for maybe intake planned for nearest future) So, here's what I've learned so far:
1. EC Euro+Drive - $800
+ Three stages in one box
+ Best customer support out of the options available
+ Most popular by far and seems completely safe and well tested
- Allegedly less power and "clunky" throttle compared to other tunes
- Their power numbers look way too unrealistic, showing 200whp with stock turbo
- All the ranting about dynos and badmouthing competitors
- I guess I've been banned on 124spider for mentioning two items above
2. Tork Tune - $800
+ Used in GWR's 124 build
+ Reportedly better throttle management and power curve
- Their website is uninspiring and they make quite underwhelming claims as in "We add right around 30 WHP", but no dynos, no specs of stages etc.
- Unclear how the tune works — is it preloaded or custom made, what about updates and other tunes etc.
3. OpenFlashTablet - $500
+ Same handheld as in EC but $300 cheaper
+ Stage 1 preloaded, any custom tune is $250
+ Open firmware for manual/local customization
+ Logging, which could be useful on track
- Few real users found, no conclusive feedback on power/reliability
- Reportedly support is very bad with long turnaround times
- GWR's build started with it, but then switched to Tork. Wondering why so.
4. Local tune shops (in my case — upsolute.com franchise) - $400 for one flash
+ Flashing price includes dyno tests to verify the change
+ Claim only 16hp gain, which is ridiculous for the price. Unless they mean that resulting 180hp is actually on wheels — then it's fine.
- Next stage is another $400 on top, which makes it cost as an EC device.
I was initially choosing between EC and OFT, but after that ban, which I think is likely connected with EC, I'd rather go with Tork / OFT.
I would really appreciate any feedback of 124 owners on either of the options (or anything I might have missed) — mostly interested in OFT, as the combination of price and updatability potential looks very appealing
