![]() ![]() I'm more inclined to think this is an issue with either N75/WG Actuator. Also when I said 1500mb I was already deducting the atmospheric pressure, so it's actually 2500mb. 80s under boost) which was also what REVO tech told me to strive for.īy reverting back to stock I meant stock mode. My lambda values also seem to be fine (high. I did however dropped the fuel to 7 as was advised by someone from REVO (put it at 6 originally but was getting too much ignition timing correction with Timing 7), now I have it at B8 T7 F7 and max timing correction I'm getting is -3 in only one cylinder on a really humid and hot day. Thanks for the reply, I know it's not actually a "stage 3" but that's what REVO calls it when you swap to a K04, I have checked the settings since I do have the SPS+ switch and I've done tons of datalogging, my REVO settings appear to be fine, don't think it's the ECU map. Quote from: Pudding on August 28, 2020, 02:28:26 pm I thought Revo Stage 3 was for hybrid turbos? ![]() Ideally you need to see 0.82ish lambda in boost for best power, which is around Fuel 8 from what I've seen.Īssuming all the hardware checks out, I'd suggest an email to Revo.but they will just tell you the same thing.check the hardware or back the settings off! If the EGTs get too high and the ECU backs timing off, you won't get full boost.hence try less timing to begin with. The requested and actual boost are theoretical targets if everything is working as it should. Remember you have put a K04 onto a K03 engine which has a higher static compression ('10.5' vs '9.8') so you won't be able to run K04 ignition advance. I think you need to speak to Revo mate.īefore doing that, back the timing off to 5 and monitor timing pull with VCDS. Stock K04 spikes 1.2 bar and holds 0.9 so that's a weird request. Revo told me to use B1 for stock after many chats with them.Īnyway, the fact it's requesting 1500mb (8psi guage) points to a problem. Stock mode is nothing like stock, it's way more powerful. If you want stock boost, use B1, not 'Stock mode'. When you say reverted back to stock, do you mean 'Stock mode' or Boost 1? I thought Revo Stage 3 was for hybrid turbos?įor a K04 you would usually go with their S3/Ed30 Stage 2+ software, which requests about 1.5-1.6 bar from memory (21-23ish psi)ĭon't forget these ECUs measure boost in absolute, not gauge, so you need to deduct 1 bar (1000mb) from the requested and actual to get your gauge pressure. I appreciate any help you guys could provide me, this issue has been driving me insane for quite some time now. You can see how when the ECU is in stock actual matches up with specified easily and even passes it. ![]() Once I reverted the settings back to stock, this is what I got I did some logging (requested vs actual boost) with the settings at B8 T7 F9 Checked for fault codes using VAGCOM - nothing comes up Deleted PCV valve (replaced with oil catch can) Other things I've done trying to fix the issue: I've checked every boost pipe/hose, make sure all the clamps are tighten up, visually at least I haven't been able to find any boost leak. Now, I don't know if it's just a coincidence that this happens at the same time I installed WMI, I also replaced the oem throttle body pipe with the CTS turbo one and replaced the intercooler hoses. I have a Borg Warner K04 installed with Revo stage 3 software (have had it for almost 4 years now), my car would usually boost at peak 25-26 psi and hold around 23 psi, but ever since I installed the WMI and changed the settings using the SPS switch (upped the timing from 4 to 7) my car hasn't been boosting as before. ![]() Hey guys, I need some help here, my car is 08 GTI TFSI, recently I've been adding some mods to it but the main one being a water/meth kit. ![]()
