Ancient post bump, but while googling for this feature I found this. the solution I found was to use the XY plot function (logging>xy plot and then set the parameters against x/RPM) In the display tab you can configure lines or dots. I like this view too sometimes. I would like to have the possibility to filter logs too, by pedal for example. maybe an idee for a future update?

Hi Andrew, have you checked your dwell time table? if the voltage drops this can have an effect on your coils. But of the voltage drops I would first take a closer look at the generator. How is the tensioner for example?

Wow Okey that was an easy fix! My fuel maps are spot in so I did not bother to wire in the lambda yet, only forgot to turn cll off! I think my previous problems had something to do with the wiring and I have assumed the issue was the same. I had pedal/tb codes before that are now solved. thanks a lot for the pointer! I fee kind of dumb now, but the car is running as good as expected.

Hey guys, I have a very annoying issue with my TTLINK G4+ pnp ecu. The ecu is wired to an Audi 8L loom but fitted inside of a 1981 VW bus. This is a 1.8 with GTX3076II with bi fuel. Log on LPG but will do the same on petrol. The issue started out intermittently, sometimes the engine would hold back as if entering anti lag. At first I thought it was a wiring problem or pedal issue, so I swapped out the pedal and fitted a full "new" engine loom, taking extra care for a good power supply through 3 relays. After refitting all electronics, I still have the issue and today it happened almost every minute. I can power cycle the ecu and drive on with full power straight away, but after around one minute the engine starts to hold back again. If I try to maintain speed, the engine rpm will slowly decrease so I keep adding throttle untill the engine is building around .5 bar of boost and still dying. Sometimes accompanied by misfires or pops in the exhaust. It feels like rolling anti-lag, but I cant see anything happening in the ecu. Timing stays about the same, injection times do not change. No lambda in this log. For illustration I attached a screenshot, from 10s onwards the rpm is slightly decreasing while throttle is applied, from 445s I think you can see the misfire in rpm ROC. Knock was disabled, turned it on now. I have 2 logs attached that show the issue, and would very much like some help in troubleshooting where to look next. I thought of coil failure, but it would be weird that I can fix it by power cycling and get straight on the gas again. No ecu fault codes, and ecu is running the latest firmware (updated this morning). Any pointers? Kind regards, Tijn Log 2022-09-14 5;58;57 pm.llg Log 2022-09-14 5;59;19 pm.llg

Oh wow, totally missed that one. Maybe that has caused the confusion! Thanks for your swift replies! Hope to get back here with better questions soon ;-)

Thanks for the clarification Adamw! It's a shame it doesnt control the wideband by itself, but luckily I still have my old LC-2 controller, so I'll wire it in. If this is final, Link should change the description of this PnP ecu though: on the website it lists "Built in Wideband controller" under analog inputs. http://dealers.linkecu.com/TTX

I researched the number and it turns up as LSU4.21. However, if it is not supported by the ecu I cannot get any real values from it, right? The measured voltage is the measurement cell but the wideband data comes from the pump cell. My innovate calibration is in the drop down menu, so that should work. But the real question now remains: If I hook up a 4.9 sensor to the OEM harness, will the TT Link recognize it or do I still need a seperate controller?

Hello there! I am totally new to the Link community, I did all my previous tuning on factory ECU's (Bosch ME7). Since the project has very little OEM parts, I decided to switch to the Link pnp ecu for the 1.8T engine (TT Link). I have done some research, but cannot obtain a solution for my issue: I have a WBo2 connected to my factory wiringloom (MY2000+ 1.8T), and I would like to use this through the pnp ecu. However, the basefile comes with narrowband set up as standard. I have tried changing it to Lambda1, but then there is no response. If I keep it at narrowband, it reads a voltage (0-1v). Maybe I have a 4.2 sensor? Are there ways to make use of it, or do I need to install a new 4.9 sensor and rewire the harness? I have an old Innovate controller laying around that i could use for the moment, but was really hoping to just plug n play... Regards, Tijn
