    Rossobianconero got a reaction from TTP in M5X Pnp Road Tuning   
    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?

    The gauge will see lambda and multiplier for what ever the manufactured decided and show it to you in AFR, because you are reading the signal coming from the gauge I would just tell the ecu stoich is 14.7. Because you are actually seeing the equivalent of lambda multiplier by 14.7 (guessing AEM is using 14.7), just run them as pump gas.

    I am with you @Oprah_152 on the table allocations, is easy to run out. But sadly there is no way we get more, is a hardware limitation from what I know. The G5 is going to have more but no information about it yet.

    Rossobianconero got a reaction from k fuku in 4D and 5D need more resolution   
    I make a MathChannel to keep track of AFR Error, so if the AFR is for some reason leaner that what it should be (specially at high boost), make a 4D table on the ignition correction to retard a little bit the ignition, just to be extra safe. But the 4D and 5D table dont allow decimals on the math chanel Axis, it goes from 0 to 1, wish mean that i cant make no adjustment to the ign with less than 0.3 of AFR error, and then a big adjustment with over 0.4 AFR error at high loads. I'm guessing it can be fix, and save some engines.

    there you have it, like Adamw said, it just need more tuning. Usually you need to take quite a lot of fuel at higher rpm because like Adamw said, the efficiency of the engine drop (maybe no so much in a high na revving engine)

    Rossobianconero got a reaction from hung_lo in MX5X in NA6 Miata with VVL engine (BP6D)   
    I have a couple of customers with the 1.8 VVT engine, they run great on the LinkG4+ wiring ecu. And they upgrade from the MS ECU actually, one of them because of a faulty regulator on the alternator. Without warning the alternator start to make spikes of voltage, and burn the MS ecu... We wire in the Link (without knowing about the problem), after just a few seconds of the first start, the engine shutdown. Looking at the log, we saw voltage of over 18V, the ecu cut the fuel and save everything, the ecu never burn like the MS. I have work with MS ecu, and have customers with them on, I really don´t like it...

    Rossobianconero got a reaction from AbbeyMS in Target afr protection   
    I work with a lot of race cars, and usually my aproach is to leave it to the driver, I dont wont to shutdown the engine in the final corner if he is fighting for the championship, I leave that to him or her to decide, in that case the best way is a Dash, and make different alarms,  he or her can decide what to do and when. In those car I just make corrections to try keep everything undercontrol if something goes wrong. If is not that series the competition then aggresive protections is a good way to save the engine. 
     
    If you just need to turn on a light to warn the driver, you can use aux that under over X afr and X amount of load turn the light.

    Rossobianconero got a reaction from Booston in Make fuel cut softer   
    or the other option is to detune the engine before hitting you fuel cut, let say you have your fuel cut at 7000rpm, you can lower the power of the engine before that rpm, so the driver knows that he is close or is just slower to hit, you can even rise the fuel cut to 7100rpm but lower the power output of the engine that no driver is gonna push the engine that high because is clearly not making any more power. Lower the boost, putting more fuel, or just taking a few degrees of the ign table, or all of them. Is just another way.

    Rossobianconero got a reaction from Fotis in MBT blended fuel?   
    i think is something around 104... but to be honest doesnt matter as alcohol cool everything they usually performe like higher octane fuels in some occations... you will not be octane limited to tune that car, we have 97ron pump gas here and I have tune 250whp 2.0 B series without problems reaching MBT, as the B series ussually you dont have really high CR as other engines (cause is very difficult to get more without modifien the combustion chamber on the head). 12 or 12.5 is ussually what you get from those engine and with massive cams to make the power you shouldnt run into problems with knock, be aware cause you never know but with methanol you are gonna be fine.

    Rossobianconero got a reaction from MattR in Ignition timing question   
    you just need to tune your engine, any respetable tuner should do a good job on a NA build like yours. I have tune some BMW engines and if you ask me they normally run from 25-28 of advance at wot with everything tune (good fuel map). The base map is always safe so is normal that a final tune has more timing and normally less fuel aswell. If you are gonna tune the engine I would start with the base map not the one from the rally car. Tune the fuel map and then go to the dyno and tune the timing.

    Rossobianconero got a reaction from Bram in SR20 CAS - Crank Angle Sensor.   
    dont forget to follow the instructions to configured that sensor on the software, is very easy to do but it have to be done or the engine wont start:
     
    The Nissan 360 Opto Trigger Mode is designed for use with Nissan optical Crank Angle Sensors (CAS) that have 360 evenly spaced slots and 4,6 or 8 different width slots. Digital trigger decoding uses all of the 360 slots to achieve precise engine position calculation.
     
    Of the 4, 6 or 8 slots, one will be wider than the others. This Widest Slot is used by the ECU to determine the engines position in the firing order. As the width of this slot varies depending on the exact CAS used, an automated setup procedure has been provided.
     
    Note: THE ENGINE WILL NOT START when Test ECCS Sync is turned ON.
     
    Setup Procedure:
     
    Setup ECCS Trigger Decoding as follows (Read the entire process and ensure you understand before starting):
     
    1.Ensure the 360 slot signal is wired to the ECUs Trig 1 input.2.Ensure the 4,6 or 8 slot signal is wired to the ECUs Trig 2 input.3.Switch the key on, do not start the engine.4.Connect to the ECU using PCLink.5.Ensure all Configuration options are correct.6.Under the Fuel heading, select Fuel Setup. Set Injection Mode to OFF. This will prevent the engine from starting.7.Under the Triggers heading, select Trigger Setup.8.Select Nissan 360 Opto as the Trigger Mode. Note that this will initialise all trigger inputs to default values. The default values are as follows:·Trigger 1:·Trigger 1 Type = Optical/Hall·Trigger 1 Pull up = ON·Trigger 1 Filtering = Level 1·Trigger 2:·Trigger 2 Type = Optical/Hall·Trigger 2 Pull up = ON·Trigger 2 Filtering = Level 19.Select the resolution mode. Select Low Res Mode = ON for engines with aggressive cam shaft profiles or lightweight flywheels. This will provide improved timing stability on engines that have large variations in CAS rotation speed per revolution.10.Set Test ECCS Sync to ON. This will put the ECU into a special mode where it will automatically calculate the position of the widest slot. Note that in this mode the ECU will disable both fuel and ignition. Enabling this function will also initialise the ECCS Widest Slot value to 0.11.Open the Triggers/Limits tab of the Runtime Values window (F12 key).12.Crank the engine. This will start the widest slot calculation procedure. This procedure will take about 4 seconds. If the procedure executes correctly, the following should be observed:·The Trig 2 Signal run time value will display YES first, indicating the ECU detects a correct 4, 6 or 8 slot trigger signal. If this value displays as NO during cranking, check sensor output and wiring.·Trig 1 Signal runtime value will then display YES, indicating the ECU detects a correct 360 slot trigger signal. If this value displays as NO during cranking, check sensor output and wiring.·Finally the ECCS Sync runtime value will display YES when the process has finished.·ECCS Widest Slot will change from zero to a value indicating the width of the slot (typically between 5 and 25).13.If after 10 seconds of cranking the ECCS Widest Slot value is still zero, an error has occurred. Recheck all trigger wiring and test the CAS output. If this is OK, repeat the entire procedure.14.If the process completed successfully, switch Test ECCS Sync to OFF.15.Remembering that the Injection Mode is still set to OFF, crank the engine and check that a stable engine speed (RPM) is obtained and the value is consistent with a typical cranking speed.16.Set Injection Mode back to the desired option.17.If all is OK, perform a store to permanently save all settings to the ECU.18.Set the base timing before attempting to start the engine (DO NOT JUST TRY STARTING THE ENGINE!). 
     
     
    I just copy paste the info that you can find on the help section of the software, is really usefull you should try it you will probably learn about a lot of stuff searching for your answers.
