Jellybean Posted October 19, 2016 Author Share Posted October 19, 2016 I was doing more digging last night in Sequential operation , By no means am I expert in MoTec calibration but it just does not look right to me. the Duty cycle tables control the valves, the Duty cycle tables to me run the Turbos in Parallel Trying to engage with Dave Rowe again, I think Fraser is still in China , even if I can at least get an hour of Dave's time to advise me, if he would be interested in working with the car Hopefully MoTec will respond http://www.motec.com/forum/viewtopic.php?f=53&t=3412&sid=b19f7fe2eeeaaab8963c6b417a5cabbd Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 19, 2016 Share Posted October 19, 2016 I am *NO* mapper, but on a cursory glance they look fine, the VSV's are either on or off ( zero or 100% duty) relative to engine RPM and throttle opening maps. What are you seeing as incorrect? Whether the timing of the VSV switching events is correct relative to throttle opening and RPM I have no idea, but Fraser did all this on his 2JZ-GTE VVTi manual, and did once run through his notes on when the events occurred on a stock car and ECU.

Wez Posted October 19, 2016 Share Posted October 19, 2016 (edited) Having them both open at 4000rpm above 50% throttle would basically be parallel as per my comments on your dyno plot when this was initially mapped. The VSVs should to be staggered to provide sequential operation, if you have the AEM Pro software installed you can check the 2JZ-GTE basemap for good starting points EDIT: just to add I recall there being three VSV to activate not two.

Mike2JZ Posted October 19, 2016 Share Posted October 19, 2016 Those Aux output's need to be differentiated by RPM. 1st turbo, VSV, (AUX1) should have 100% duty cycle earlier on in rev range (~2000/2500rpm), whilst 2nd turbo (AUX2) should have full duty cycle kicking in around (3500-4000) Only thing I don't know is if AUX 1 needs to return to 0%, remains at 100 or requires another partially open value after AUX 2 kicks in. Understanding the logic of the stock system is half the battle here, after that the implementation looks simple enough with the interface Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 19, 2016 Share Posted October 19, 2016 Sorry, I was assuming the maps were for parallel operation, hence me saying I don't know about timing (for sequential operation). I was as clear as mud, of that I am sure Yes, certainly for sequential operation the timing would need to be staggered, and as I said, Fraser data logged exactly how the stock system did this. Good luck with it, `tis only money.... Quote Link to comment Share on other sites More sharing options...
Wez Posted October 19, 2016 Share Posted October 19, 2016 OK I loaded up the AEM Pro Software and checked the 2JZ-GTE install guide and checked the outputs in the base calibration, as I suspected it does indeed use three VSV and they are staggered Just to add, when I was running an AEM on stock twins we spent a fair while fine tuning these to get the sequential system running very nicely. You need to go back to your mapper with this as it doesn't appear they have done what you requested. Quote Link to comment Share on other sites More sharing options...
chazuk Posted October 19, 2016 Share Posted October 19, 2016 This might help stu hagen did custom outputs for the vsv's on his vipec ecu Quote Link to comment Share on other sites More sharing options...
Jellybean Posted October 19, 2016 Author Share Posted October 19, 2016 (edited) Thanks for the help , hopefully Dave gets back @Wez , my mapper did not plumb in the EGBV, said probably do not need it I just wanted my car back at that stage! To be honest I am fed up dealing with him , what to get a new mapper , Dave or Cody maybe EGBV This allows some exhaust gas to bypass the EGCV and join the output of the first turbo. It serves two purposes - one, it prespools the second turbo by allowing some exhaust gas flow through it. Two, it controls the amount of exhaust gas going through the first turbo in much the same way as a wastegate - therefore controlling the maximum boost pressure generated by #1 turbo.

Jellybean Posted October 19, 2016 Author Share Posted October 19, 2016 (edited) Also noticed My Sytec FPR he installed is "Manifold Pressure Referenced" not Ambient Not too sure of the implications of this Edited October 19, 2016 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
Wez Posted October 19, 2016 Share Posted October 19, 2016 The EGBV is the first VSV to be activated Quote Link to comment Share on other sites More sharing options...
Jellybean Posted October 19, 2016 Author Share Posted October 19, 2016 The EGBV is the first VSV to be activated I know , this is what I have to deal with! I just confronted him now , My mapper said he set them that way as it is smoother even though I requested they are set sequentially , had a lengthy conversation pre and post mapping about it; He told me he set them up in sequential Quote Link to comment Share on other sites More sharing options...
Jellybean Posted October 19, 2016 Author Share Posted October 19, 2016 He got back the FPR setting is indeed incorrect , should be "Manifold Pressure Referenced" not Ambient Said it wont cause an issue, will see what MoTec support says Quote Link to comment Share on other sites More sharing options...

Jellybean Posted December 12, 2016 Author Share Posted December 12, 2016 Had her Calibrated again with the Fuel Pressure sensor , Car is alot better on fuel ; All three VSV's are Wired in, the Sequential is a no go , mapper tried to swap around inputs but could not get the fuel pump to work Did a dyno run to set the FPR correctly to run off Manifold pressure and to calibrate the fueling model with the Fuel pressure sensor , she spools a little earlier with all VSV's plumbed in Traction control is wired in via wheel speed sensors but no calibrated still Still had the ECU illustrating error (Throttle Position Sensor diagnostic Closed warning) , I set the Throttle scale and offset myself so the ECU knows a reference scale, when the Throttle is full depressed and fully pressed , error is gone and car idles better Was talking to John Reed , going to get John to setup the car in sequential and traction control, John said it was fairly easy My memory is a bit rusty on the sequentials but I seem to remember only needed two of the three solenoids. But either way we should have plenty to work with in the package. AEM did it very simple based on rpm mostly (and load/throttle) and we can easily do that using the Auxilliary Outputs (I believe you have them highlighted in one of the screen shots). You would set the table axis up (as you had shown) and then simply put 100 in the table where you want that output to be on, and 0 where you want it off. See attached picture. Also make sure you set the activate parameters appropriately. If it is inlet manifold pressure, set it so the output will come on when you want it to. If you don't want to use those parameters (and just let the table control it) then set the min to 0 and the max to 500 (inlet manifold). Also make sure you setup the fuel and timing trims on Aux 1. Just zero it out if you aren't using them (set mixture aim to 2.0 if not using it). Hope that helps! Should be pretty easy. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted December 26, 2018 Author Share Posted December 26, 2018 Just talking to John Reed , he is adding automatic transmission support to his firmware ; should be due for release in January when Motec re-open ; these firmwares needs to go via Motec release process Quote Link to comment Share on other sites More sharing options...

Jellybean Posted December 26, 2018 Author Share Posted December 26, 2018 Including support for Tiptronic `boxes? Will ask, here is what he said Early January is the plan! MoTeC Australia is closed clear past the new year so nothing will happen until they reopen. I am trying to get automatic transmission support added in the meantime but if I feel I am not close on that then I won't hold the update Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 26, 2018 Share Posted December 26, 2018 That sounds like it could make the M1 popular if the Tiptronic control is properly sorted i know from experience that getting it working PROPERLY is not trivial!

Jellybean Posted December 26, 2018 Author Share Posted December 26, 2018 (edited) New firmware from 2017 is fantastic, GPR package exposed, before it was dumbed down, hidden, due to mappers who may not know what they are doing Edited December 27, 2018 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...

Jellybean Posted January 4, 2019 Author Share Posted January 4, 2019 From Cody Cody Phillips yeah we’ll have some plug and play adapters for the auto. It will need to be in a M150 ECU in order to accommodate the trans and have any reasonable I/O leftover for other features. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted October 12, 2019 Author Share Posted October 12, 2019 Oe auto trans control will get released shortly Quote Link to comment Share on other sites More sharing options...
