yea, my bad. I mean engine adaptations, not transmission. Your tranny quick charge pressure looks pretty good.
The gauges snapshot. Is it on idle? Isn't your rail pressure super low? My rail pressure is 700psi at idle (sensor after hpfp). I agree at this point you need ISTA to show everything, even though MHD got most of it. There is a lot of info on the forum about the codes, to me you have 3 routes to take care of. - LPFP, HPFP pressure (that HPFP position error, don't know what it is) - coolant temp sensor, thermostat clamped open (defective part?); pump and bleeding is good? - MAP, MAF sensors, vacuum tubes leak? is your PCV (valve cover) good? The unsuccessful start I don't know. I'm hoping you fix these issues will help with the start/idle. Last edited by mashpotato; 05-10-2021 at 02:17 PM.. |

Thank you guys for your help! I got a response from the shop and they fixed several of these, the car is out of limp mode now. It seems like the HPFP was not engaged with the camshaft. It still has a problem with the thermostat getting stuck in the open position. He'll take care of it next time I bring it in. As for now, do you guys know what I need to refresh the suspension? It has the Adaptive M, and it rides like shit, and a strut is leaking, so I'd like to replace the whole thing as nothing has been replaced and it's sitting at 135k. I'd like to use OE and not lower the car.
Car feels pretty good at the moment, except for the Thermostat that causes the Fan to go 100% and the Oil Temp to not move? And a new Transmission code:/ |

Bilstein also makes plug and play B16 coilovers now, and KW has had a plug and play coilover set for a bit, but I have read that the KWs are significantly firmer. There's also the option of going to normal coilovers without adaptive features and coding out the adaptive function or buying the expensive EDC delete kits.

The bilstein b4 damptronic dampers are meant as a direct replacement for stock. There will be no lowering. Bilstein bills them as oe+. The b6's are going to be an even stiffer/sportier option.
With coil-overs there will be a mild drop even at the highest setting. Your options if wanting to maintain edc capabilities are: Just dampers: bilstein b4 damptronic, bilstein b6 damptronic. Coilovers: bilstein b16 damptronic. KW DDC. If you go the b4 route please post your impressions. I also want to keep my edc and keep stock ride height. I also don't want a big increase is stiffness and harshness. I really want to hear if the b4 is much improved over stock adaptive. Last edited by 435gc; 05-23-2021 at 08:59 PM.. |

The dampers dont dictate the drop, the springs do. For oe replacement get the B4 and an OE type spring.

Dropping the subframe is not as bad as people think.

Trans - go pure, dont try and swap in a different unit Meth - could do it if you need additional supplemental fueling |

EU5 S63 injectors should suffice for 650-700whp on a rich tune (Full E85). Go with Nostrum or Precision Stage 2 injectors for anything above that. However if you can afford it, just go straight to the stage 2 injectors - the headroom will be nice.

HPFP is the limiting factor... the upgraded LPFP is doing nothing with stock HPFP. You should have upgraded HPFP first.

Depends on your turbo and fuel... big turbo will make more power at lower boost than stock turbo. Assuming you are not octane limited you can probably make low-mid 400s on good pump gas with a big turbo. The power ceiling its really low with stock HPFP because unless you are running race gas you need ethanol to make power and the stock HPFP will not support more than like 16-18psi at E30. But these are all ballpark numbers since how well your turbo is flowing and your other mods will affect that

Like 400ish hp depending on fuel type 😆 the lpfp is good for like 500 or more.. these are very rough numbers and not exact but the stock hpfp is trash and it's funny.
