Anyone used the Renntech tuner on Their newer generation GLA45? If so what was your experience? I’m talking about the 375hp version of the GLA? I know this model is still under warrantee so some may be apprehensive.
Very interesting and thank you for that I had no idea that the 2019 went to an electronic DV. What did the earlier models use? Yes the Renntech tuner was designed for the original 45 I’m not sure why they haven’t bothered fine tuning one for the 2019 model but I think I will ask them. Probably supply and demand since 2019 would still be under warrantee.Yeah, good question
I have a 19 as well and come to the platform from a 500ish mazdaspeed6 which is still on stock air con, ;-)
so yeah, I so wanna fuq with it, but just spent a day with a loaner, while getting my 20K prepay done, (4200miles on the clock, but, warranty, yeah?)
As you arre proly aware, there have been some itereations to the engine, and the first did not use a DV
our 19's use an electronically controlled DV
Most aftermarket DV are 'kits' involving a vaccum "T" to run a conventional DV
I personnally would not leave that kind of control on the table, IE give up the ability to control the DV independently
whew, so, I was thinking tune, but the warranty...so not gonna do it. Later tho, yeah, When that time comes, unless the tune was developed on a 375 (with DV), on a 4 wheel dyno, I would not use it. and I think many come from 2015's so, caveat emptor
Also, this sweet ass tranny, has a brain, and feelings, so if you twist on the input shaft to hard, the trans, will tell the ECU to stop doing that. negating your efforts
Dunno where I saw this, so do not state as fact, But aside from the above, the added some suppemental fueling.Look to what it took to go from 375 HP for 408 HP (416 PS), a 33 HP increase:
Complete redesign of the architecture of the engine, turbo is now at the back, intake is now at the front, they basically turned the engine around, for 33 HP.
As far as potential changes, I think that for the new BPV, the compressor cover had to be redesigned. Once that door is open and MB has to pay Triple K or Garrett to recast their compressor cover, then changing the trim of the compressor impeller wheel comes in as peanuts, might as well pay to do that too, so, you never know..
They changed the exhaust camshaft and tune.
yeah, stuff like thisIt makes sense that the OEM tune should be pig rich, this is to be expected. They work on ignition and cam timing and boost comes in after the fact, kinda opposite than the aftermarket tuners.
Tuning by timing with pig rich fueling is how you can roll out an engine with a warranty like the factory does. It's said that it takes hyper-accurate knock knowledge that the factory gets from advanced simulations and from... breaking engines through testing.
