    So fitting capacitor on 1.3 is defenitively not needed anymore? We add one on all our installation up until now. 

    We haven't use them, and we haven't encountered any problems.

    Copy that, thanks. 
     

    I’ll be passing on the 1.2 and just getting a newer one then. Not worth building in a potential headache. 

    and that's exactly what we choice here to, no more v1.2. 

  3. With the old v1.2, sometimes we couldn't even share the power source to the ecu, sometimes the can lambda work, sometimes it would not. Since the 1.3 we haven't seen that problem, but every car is different so could be just the different stock wiring on the cars not necessarily the can lambda. With the v1.2 we try everything, capacitors, etc. The only thing that actually fix it was a very good power source. Sometimes the one that normally should work... well it did not.

    ok how do you attach that pin to the can keypad to make it ground out the fan relay

    You don't, the keypad will tell the ecu you want the intercooler fan to turn on (this through CAN), then the ecu will activated the output to trigger the relay that will activate the fan. 

    If you post the File we can help you setting up.

  5. what is your engine setup? what cams are you running? and we will need a log to see what is doing on the pitlane and that drop that you feel when the vtec kick in. You are running just one fuel map, normally with vtec you want 2 fuel maps one for each cam but, you can get away with just one if you do it right. And on race cars I like to have another correction for the VTC and fuel map so if is running a little bit of the vtc target, it will still perform.

  6. Like @atlex said, modelled fuel equation is superior to traditional, but I have some problems in the past when we did not have enough sensors to run it correctly. At least you want fuel pressure, the equation request for fuel temperature as well to be accurate, I have done it without the fuel pressure sensor and so many times the fuel system is not doing what it supposed to be doing, so run the fuel pressure sensor. I had never done it without fuel temperature so cant  comment on how important is at the end of the day. You will also need a very good information on the injectors, do a 3d table for deadtimes etc. 

    About the lambda target, in general you want to be as lean as possible for power, just put enough fuel to keep it safe, how much? you will have to try on the dyno, but like atlex said, is better to start on the rich side to be safe. Then with everything tune and hitting your lambda target etc, and with you listening for knock, you can try on the dyno and see how much power you are giving away with running rich etc. And also depend of were you are what fuel you run etc, sometimes you will make more power running richer and more timing that running lean with less timing.

    Boost control is set manually as of now. I have not messed around with the knock monitoring in the link settings. Outside elements when driving make it difficult to keep the engine in a complete cell so Ive tried to let the mixture map sample while I focus on the road. These engines are knock limited but most issues are reported over 18psi depending on supporting systems ect. 

    I have tune some of those in the past, and I would say that you need knock control when you want to go into power runs, you never know when they are going to be knock. With a good driver you can hold the engine in one cell, but I would say just make "pulls" at X amount of vacuum from low rpms to the limiter and then re adjust the tune until you have it perfect.

  8. Don't worry about the dyno, you can make a really good fuel table on the road, is just more time consuming. I will just tune it "old" school, just get someone to drive the car for you and you tune the fuel table. Are you going to run knock control? and what boost control are you going to run?

    one map run twice so each bank has its fuel and timing calculated for it or the same fuel and timing applied to both?

    at least on the tuning side, you have only one ignition and fuel table (more in reality but, lets keep it simple ) , but the closeloop is per bank and it will correct each bank as it sees necessary. Can not remember at the moment if you can adjust each bank on the stock ecu, like putting more timing on one cylinder that other but I would say probably, but timing is running the same base for both as the fuel, but runs full time closeloop per bank.

    Right Click on table -> Import/Export -> Export to Clip Board OR Export to File, use the imports for loading a setup into a table.

    others ecus, when you open and create a correction for one cylinder, it will ask you if you want to add the same table for each cylinder, that save some times, is something that could be added?

  11. On other software you can save your tables, for example ignition correction per cylinder, so every time you add the correction to a cylinder on the link you have to erase or adjust the premade axis instead of just load a setup. Is by no means a deal breaker but it would save me quite a bit of time specially on a V8. I don't know if it is something that can be add to the current software. But would be nice.

  12. If you are using modelled fuel equation, and you have a FP sensor you should change your fuel system type from map reference to fp sensor. I usually only use modelled with a fuel temp sensor as well but, I'm guessing you can get decent results without it to. If that O2 sensor is reading correctly you are way way to lean to be on boost, are you using any type of knock detection while doing this? Your charge temp correction doesn't looks right, and when you are using modelled you don't use a IAT correction for the fuel. If it is as lean as the O2 show, I would abort the run, put more fuel on the fuel map and try again. 

     

    On the boost control, you have to setup the boost target base on something else that MAP or MGP, a very common map would be TP vs RPM. And on the wastegate map, you use boost target on one and RPM on the other axis.

  13. the same file that you posted with knock control "setup", is NOT SETUP you will have to check what is knock at what frequency you can detect knock better with the ecu but, it will give you a idea of how would looks like. I didn't adjust the axis on the trim tables but you get the idea. If you follow the help files instructions you will be alright, for me what it work best is when I set it up for the first time is using my own knock detection system (so i can actually hear the engine), clears knock are easier to detect in both system.

  14. I'm guessing when vtec activated the engine dies... you have a fuel map for vtec on, which has not been tune or calibrate is at cero, so any time you will go to vtec it will stop injecting fuel (falls on its face). And like koracing said, your fuel map on boost at least on no vtec is max out, that doesn't make sense. At first look the timing seems conservative, should be a safe start but knock control is going to be necessary even with e85.

    Many tables you can't actually edit. This includes the Boost ECT Target Trim Table.

    Others are idle control Startup Offset and AC Offset.

    I never really had to adjusted but I check and yes, you cannot edit the Boost ECT target trim. If you need that correction with more temp, then you can use the GP trim and make your own. Sadly, that limits the options to do other thing with that table but...

    I know my case is uncommon but my car being air cooled and running quite hot I'm well over the fixed scale of all the ECT tables..

    I'm running around 130-140°C and I max out the sensor at 160° on track or in traffic..

    It would be nice if the scale could be edited so I could implement some safeties.

    For instance the boost target trim table stops at 140..

    Since the car heats up quickly I guess I could deal with simply render the axis editable so other users wouldn't be messed..

    You should be available to edit the axis of the tables by pressing X. You can make the tables as you wish, the ECT can even be 3D if you want

  17. Is 93 us? so like 98 ron?

    Probably Adam can help us with the 2 knock sensor into one knock signal, normally you would run one knock sensor one signal input. So I don't know if that could cause that problem. It should not be even close to knock on 97-98ron on that lambda and timing. Are you using any sound confirmation of the knock? are you using your own knock detection system? That would confirm it either way. My guess is that or the frequency is not the right one, or you cant run two knock sensors on 1 signal input. You will probably end up with a gain per cylinder that is not all at 1.0 when the knock detection is setup.
