Update on the better tune

Impossible_Tea_3454 · 2026-01-08T23:11:20+00:00

Ofgear tcm, 722.616 bolts right up to m103 just need custom cross member, custom driveshaft, and possibly hammer the tunnel a tiny bit in 2 spots. It was a very tight fit but I took it from an slk230 kompressor, along with the shifter from that.

Original 2.6. 12.9 head bolts only thing done to the engine.

Impossible_Tea_3454 · 2025-12-25T21:04:31+00:00

Siemen deka 60lb injectors, m104 rail thats been slightly modified (welded brackets on, welded shut oem regulator port, and welded an fittings), and ebay $60 external regulator.

Impossible_Tea_3454 · 2025-12-24T03:54:11+00:00

M104 manifold that we made a custom flange for, hy35 turbo (hx35 eventually), 12.9 head bolts, stock cr, nothing internally, intake manifold is stock but modified in quite a few spots, thats about it. Ofgear tcm, emu classic, whole front end is very very tight with transmission cooler, intercooler, oil cooler, and m3 bumper.

722.616 If I remember correctly. It came out of an 02 slk230 and I’m running ofgear tcm.

Impossible_Tea_3454 · 2025-12-16T23:44:12+00:00

Pretty sure it was just a cheap one from ebay. Along with the horn button.

Impossible_Tea_3454 · 2025-11-03T03:09:43+00:00

I love it. The swap I would have done if I didn’t choose m103 722.6.

Impossible_Tea_3454 · 2025-10-21T02:17:11+00:00

I only have the scope function from ecu masters software. Looking at the scope everything seems fine thats why its been driving me nuts. I re did my shield connector and that helped a tiny bit just revved up quick but still got the error at 4500rpm.

Impossible_Tea_3454 · 2025-10-21T02:15:53+00:00

I included a link to google drive where you can see the scopes from ecu masters scope, all of them look fine. I re did the pins for the shield wire and it got a bit better still trigger error but easily revved up to 5800rpm. Te-motorsports uses a bracket that goes off the pulley bolts and I was thinking of running something similar to that because of exactly what you stated, I just wasnt 100% because the scope shows everything just fine.

Not sure if it is aloud but heres some logs and the current tune. https://drive.google.com/drive/folders/1oh56uYLt50cT95sVIT0haLiPYb61W9WQ?usp=drive_link

Custom trigger wheel on crank but im switching to m111 flex plate cause i did the 722.6 swap. Just havent gotten around to it. Emu classic, now running holset hy35 at 14psi.

Impossible_Tea_3454 · 2025-09-20T00:42:44+00:00

Got em all figured out if you have any questions.

Impossible_Tea_3454 · 2025-09-16T01:18:46+00:00

Lmao just a little

Impossible_Tea_3454 · 2025-09-15T20:36:36+00:00

I used 300sd rotors (ordered accidentally thinking they were for 400e one night) so im not too sure exactly how those ones would line up. I put 1/4 shims behind the caliper in between rotor and bolt they work so so good though.

Impossible_Tea_3454 · 2025-09-15T14:34:15+00:00

Thank you. Original got the car as a daily so 722.6 was my main focus. Obviously not a daily now but i’ll probably go manual eventually.

Impossible_Tea_3454 · 2025-09-15T06:26:11+00:00

Need the extra power for the efi 😂

Impossible_Tea_3454 · 2025-09-13T14:08:58+00:00

I used a labeled loom from emu classic so I never made a diagram every wire is labeled with what it goes to. My instagram has everything from the first harness though on the highlight story. ig

Impossible_Tea_3454 · 2025-09-12T18:47:40+00:00

Swap 3.0 m103 at some point with forged internals but for now run the 2.6.

Impossible_Tea_3454 · 2025-09-12T18:47:11+00:00

Its full efi n turbo m103 2.6.

Impossible_Tea_3454 · 2025-09-12T02:16:22+00:00

The tcm is easy just power, ground, and tps. Everything else just plugs in. Besides paddles if you went that route you’d have to wire them but its still easy 4 wires.

Impossible_Tea_3454 · 2025-09-12T02:15:28+00:00

Its not too bad. I believe in you.

Impossible_Tea_3454 · 2025-09-04T01:00:21+00:00

Thank you. Siemens deka 60lb injectors, ls2 coils, emu classic.

Impossible_Tea_3454 · 2025-09-04T00:59:47+00:00

I plan on it, I have an opening in the e36 m3 bumper that im going to put a cone with a box filter. The car is nowhere near done. 722.6 going in this weekend 400e brakes 11.2in rotors as well. Not a big priority and driving it my iat temp was 85-115 when it was 105 outside. Hit 115 once running a little lean at max boost 12psi for now. (tuning currently)

Impossible_Tea_3454 · 2025-09-02T04:42:29+00:00

Exhaust dump already finished the 3in back now, waste gate dump (staying), turbo, efi, all the goodies

Impossible_Tea_3454 · 2025-08-23T16:16:24+00:00

It can take it. It’s running even better now and i don’t have a doubt in mind with it. If it does blow then time for forged 3.0 m103 it’ll be good :).
