First off - great customer service from Craig at BIP, on Tuesday of last week I decided I wanted a TCU tune for a track day on Saturday. I reached out to Craig and he immediately answered all my questions and was responsive throughout and post purchase. I dropped it in the mail, they received it Thursday morning overnighted back to me (sent tracking info) and I had it installed by Friday night!

I’ve had a 3k stall in my car since September and while it launches like an animal when it flashes from a stop, it had some weird tendencies like holding a gear too long before shifting or not kicking down when going WOT from a stop. I think it really just exacerbates the laggy torque management feeling. A power “dead spot” if you will. The TCU tune cured this, not sure if it’s the removed TQM or shift point adjustment but from a roll the car responds so much better to WOT. I leave the ESP on below 70mph on street tires now lol!
At $450 this is by far my favorite bang for the buck mod and a must for those with a high stall converter. I’ve only had it in a few days but so far its turned my car into something that is a BLAST to drive.

Big thanks to Craig and BIP!

Glad you are enjoying it fellas. Stay classy out there

Same tune on my wagon. EC tune previously was just weird. Not bashing EC but the BIP is significantly better.

glad some are jumping on board its a must totally improves the performance and again its a must for us guys with the stall in the car.

rockthemullet

Whaaaat. What are your mods? With the stock stall and stock TCU, I have to turn ESP off at 65mph. I assumed the stall would throw more power down and harsher... are you saying the hit is more controllable?

Great to hear BIP just fixed my issue with the ECU cannot wait to get the TCU done as well

chiromikey

Any longer term updates on how the tcu tune behaves after the adaptives have set in?

super happy with mine cant wait to get to the track and test it out.

BI-Performance

Thanks fellas, appreciate the feedback.

How was it "weird" exactly ? They way I understood it was BIP was using EC tune. They got a TCU from EC and a couple weeks later they were selling tuned TCUs ....... Perhaps they found some tweaks EC wasnt aware of although I doubt it.

99lightning

Bip tcu has nothing to do with Ec.

BI-Performance

Our tune has nothing to do with EC, so please don't spread false information about our product

Sorry I meant no offense. So you guys did all your own tuning on these from ground up ? I had heard from a reputable source that you guys ordered one of their TCUs and within two weeks were selling tuned TCUs..... Doesnt mean its true but it sounded pretty believable. I just thought perhaps you guys used that as a starting point then perhaps made some tweaks to it of your own. You guys seem great and everyone on here likes you. I only said something because someone claimed EC TCU tune was "weird" and yours was so much better. They didnt give any specific examples of what was weird though... EC has been doing tuned TCUs for years and seem to be a pretty good tuner. Its no uncommon for vendors to do that sort of thing.

Peace

+1 BIP great people.

who was the "reputable source"? i had the first e/c tcu tune on my slk32 after 6 months and more tunes than i could count i ditched the setup in favor of oem. 21 afr spikes were just waiting to blow my motor.

Drove another 55 today with the bip tcu tune while doing remote tuning. trans shifted really nice super smooth and of course manual mode was awsome.

I wont name names but it was as reputable as you can get.... Personally I went with OE tune on the engine side. I did get one of their TCU tunes on special. Only drove it today. Shifts were in fact smoother and didnt notice the typical bog at low speeds as much which I didnt think was trans related Need to play with more to see how I like it. Was a half off special so I figured why not

turbo97se

To use your words, sorry I mean no offense, just wondering what your motivation is here? Are you trying to help to sell OE tuning or put BIP reputation into question? … I am unclear. The thread is about feedback on BIP TCU tune.

Log from this weekend at the track with the BIP TCU and EC ECU tune combo. just got an updated ECU file from Jerry yesterday (small blip in afr after shift 12.0). So far I'm loving the TCU tune, I think the shift points have actually raised with adaptation...but I also drive it a little more spirited than most LOL!

dllhg

I mentioned OE tune on my car to show I wasn't trying to promote EC but rather trying to shed some light on this whole "EC TCU tune was weird" statement. If the tunes are in fact the same the person saying the tune was "weird" is trying to bash another vendors product. Simply defending that. I thought that was pretty evident from my posts

All that matters is people like the tune and the company

BimmerDawg

I said I wasn't bashing, please don't twist my words. My post was promoting BIP's tune, not bashing EC's.

Before the BIP tune, the car would feel like it was slipping in and out of gear in traffic, around 1100 rpm or so. When I questioned the PO about it, he said it always did that. Full disclosure: my conductor plate did take a crap and the car needed a full transmission rebuild so my initial thought was the strange "in and out of gear" thing was related, but as previously mentioned, the PO Bart (FASN8N) confirmed that it was normal.

Again, not bashing EC so please make your own conclusions but DO NOT twist my words.

BIP is doing there TCU tunes local ?

FASN8N

Geordie, I wonder if the 1100 RPM weirdness was related to the conductor plate or the EC TCU tune? I always thought it was the SC clutch engaging? I guess we will never know, at least it is 100X better with the new BIP TCU tune
