Summary of change:
Back to MembersPage/NanassyPeter ----- 034 will release soon a really powerfull firmware upgrade for its own ECUs.Because i have one in hand,im really curious,is that planned that genboard will ever have features like this.Take a look at: http://www.motorgeek.com/phpBB2/viewtopic.php?t=10152 Its so simple,but very effective.With some even more goddies what we already have (scalable tables) this thing should kicks ass!! '''We have had most of the features added to the 034 firmware relase for a very long time. But there is a few of them that are good and is in the pipeline. -Jörgen''' All tables are fully user settable!!! Vbatt Dwell miltiplier '''Been there all the time -Jörgen''' MAP Dwell multiplier '''Good one, it's in the todo list -Jörgen''' MAT Ignition advance '''Most people will fuck up their tuning with this, but it will be added. -Jörgen''' CLT Ignition advance '''Most people will fuck up their tuning with this, but it will be added as well. -Jörgen''' Aux Ignition advance '''Good for a race car if you don't have time to tune it before the event. -Jörgen''' Baro Ign advance (we dont have a baro map sensor) '''Useless except for alpha-N and 034 doesn't have a baro sensor either. -Jörgen''' MAT enrichment '''Always been there. -Jörgen''' AUX enrichment '''Could be useful for a very small number of cars. -Jörgen''' Accel temp enrichment (we have something here ,but its just easyer) '''You can't do it both ways. -Jörgen''' Individual cyl fuel trim '''Yeah, good for VERY bad intake manifolds. EXTREMELY hard to tune. -Jörgen''' ---- *I will need really soon (ASAP!) the latest firmware with all the good stuff in it,for the Auditrigger.Please let me know when will this be avaiable,and where can i find it.Wiring is almost complete,we are only waiting for the latest firmware. ** [http://media.vems.se/code/VemsMT1.0.35.zip VemsMT1.0.35 Complete Package], there you are :) THANKS,that was FAST! *From where can i download the latest 1.0.34 firmware? Im really interested,because i started the "clone" installation,nd on that car i want to go with that. ----- * any update on RPM limiter? ** the "softrpm" limiter was merged (so they are enabled in the firmware by default and configurable) together with the ALS function, it works with ignition event-skipping RPM limiter. Currently under testing in 1.0.34. No showstoppers so far I found that the current RPM limiter is a bit harsh,still much better than fuelcut only,but not that nice that some stock cars already have.I do not know how they really work,but maybe together we can find out.I know that some of you are much more interested making VEMS controlling idle valves flawless and so on,but i think that BASIC ENGINE OPERATIONS,such as RPM limit,are more weighty.So i think we should find out how those Hondas,BMWs limit their RPM with such little hysteresis,and almost no jerk. I think that they do not cut all the ignition,but just cut some cylinders ignition event ,so the engine will not lose all its power,and movement. Please write here your comments! I don't want to argue here, but IMHO getting the engine to idle is more like basic operation than smoothing rev limit ;-) Sure,but i installed VEMS approx a year ago,and since then it runs smooth,without any kind of idle valve,just with opened throttle valve.And there are other type of supported idle valves (and not one!!) that works.I think its not that hard to install one of these (as i did earlier with other standalone system.Just my 2 cents. - You're right, there are well controlled valves already, however supporting a new one is always a big plus (and a big help for every BMW owners), if not too much work. I even didn't ask the firmware team to get support for mine, just did my measurements and own development on the firmware to support my IAC valve. (Getting help and comments from others though) Now I've got a good-working code, which finally has been merged to v30, but something is wrong now (with the merge probably), that's all. We're seeking the bug, not a big deal. ---- i did a little search,so this is how others do: TEC3: New Dual Rev Limiters with &#8216;Triple Smooth Technology&#8217;.. 1st step retards timing to a negative -12º degrees.. 2nd step cuts coil current in half.. 3rd step coil current and fuel are cut-off.. all three steps occurring within milliseconds! 034EFI: A dual stage rev-limiter is implemented in Iic to provide a smoother, more accurate rev-limiter of engine speed. In addition to the standard fuel cut rpm limiter, a programmable timing retard is also used to pull power before the fuel cut is realized. Thus, the driver will begin to anticipate the fuel cut by feeling power drop off as ignition timing is pulled back. Timing values from 0 to -50 can be used to accomplish this. For more information, see the Tuning Manual. AEM: Soft Cut Rev Limiters Utilizing user programmable stages, the EMS offers 5 distinct modes of rev limiter. With ignition retard, programmable partial cylinder cut of fuel and/or spark and full cut of fuel and/or spark, the combinations are limitless. MSD: Soft Touch Rev Control For points and OEM Ignition systems The Soft Touch Rev Control, PN 8728, is designed to be used on standard points ignition or inductive ignition systems. This means that the PN 8728 can be installed on engines with a GM HEI Ignition, Ford or Chrysler electronic ignition, any standard breaker points systems or even with an MSD 5 or Blaster Ignition (non-CD ignitions). The Soft Touch Rev Control is adjusted with plug-in modules and is supplied with 6,000, 7,000 and 8,000 rpm modules. When the engine reaches your set rpm, the Soft Touch circuitry kicks in and drops the spark to certain cylinders. These cylinders are fired on the next cycle to prevent fuel from loading up in the cylinder. This limiter produces very accurate and smooth, backfire-free rev limits. Can be used on 4, 6 or 8-cylinder engines with inductive ignitions. http://www.teglerizer.com/fi/bem/Basics%20of%20engine%20management.htm Most EMS systems implement a rev limiter, some allow a soft-cut where the engine selectively misfires followed by a hard-cut a little higher up where the engine simply stonewalls. Some limiters cut off all fuel at the prescribed engine speed, withholding it until you're 500 rpm below the limit. Other rev limiters cut off the spark (or injectors) of individual cylinders one after the other, progressively cutting more and more until the hard-cut limit is reached so that you can barely feel that you have reached the maximum allowable rpm. These soft limiters mean that the car can be used right to the rev limit without a worry. Normally the EMS will maintain the tacho signal consistently to ensure that it doesn&#8217;t go crazy. Often the rev limiting is coupled with a shift light that warns the driver that the rev limiter is about to operate and he should change up a gear. With batched and grouped injection systems, selective cutting of fuel can be dangerous since the fuel is not injected at the optimum time for each cylinder and it is quite possible for a cylinder to induct only a partial charge of fuel which could result in detonation and resulting damage. ---- '''ALS activation switch''' * A '''switch connected between GND and the ALS-switch''' input is * usually mounted on the dash. * a pullup resistor (10k between ALS-switch input and +5V) might be needed depending on the input (not needed for original "SDL" input, because the AVR's internal pullup is enabled). The SDL is a direct pin of the AVR that the ALS code traditionally uses. It is not connected to ECxx pin normally (on customers request, SDL input is connected to EC18pin16). ALS code will soon be configurable for the more available MCP3208 inputs (available on EC18pin6, EC18pin12 and EC18pin16 on most [http://shop.vems.hu/catalog/product_info.php?cPath=1&products_id=48 v3.x] depending on product options.) The ALS activation switch schematic: http://www.vems.hu/files/MembersPage/NanassyPeter/ALS/als_wsitch.JPG Note that the ALS activation input is usually on EC18 not EC36, but otherwise the circuit is fine. See MembersPage/GaborRacz/NewAlsLaunchAndOthers ---- '''ALS swith''' Currently, on this ECM (serial Nr. 337 ?), with 1.0.30 firmware no ALS activation from EC18pin16 * EC18pin16 (measured to have appr. 10k pullup to 4.4V) * and EC18pin6 (not yet tried or measured) on the ECM are connected to where you asked. You should have asked in wiki, not phone, so you would now (after several months) know. If neither of the pins activate ALS (=> so obviously not connected to SDA, which was the traditional ALS activation input; mcp3208 inputs will be recommended in the future), the mcp3208 pins should be logged to see which is connected where so it can later be configured for ALS. *tried EC36-pin6 too,no response.When i ordered the box i did not even known your phone number,hehe. For one pin at a time, issue * '''ManmllmdV''' * '''byeAA''' * '''Manmdv''' * '''byeAA''' commands and capture the result (in binary, not hex mode) in TerminalProgram. First when input > 3V and than input < 2V. Publish the captured files. This will reveal your EC18 connections. MegaTune should have a screen of the raw voltage readings of all the mcp3208 channels to make this easier. '''ALS variables''' Enabled above 1500 maxtps 40% ign retard 40 fuel enrichment 10% ALS activated revlimit 2000 am i missing something,is something wrong with these settings? I checked the EC18-pin16 and it gets 0V or 4.4V ,if swith is in position 1 or 2.firmware 1.0.30 '''A:''' In the latest firmware packages, there are indicators on the lower left corner of megatune main screen, ALS switch, Launch switch and shiftcut switch, To the right you have ALS Function active, which lights up when conditions for ALS activation are met and the functions are active. //Emil '''Q:'''Yes a saw these great features of the new firmwares, but unfortunately i cant use them.My car runs with 5 window HALL primary trigger,so maybe i can go with 1.0.34 to check this. Can u please tell me where can i find it? And Emil,thanks for the instant help/support!!! :) !! It was stuck on my laptop, here you are: http://media.vems.se/code/VemsMT1.0.34-testingonly.zip * The 1.0.34 above produces the same silly IAC behaviour. ** Why don't you make a proper report (don't forget the mcd and mct dumps!!) so we can help you adjust your config ? ** Maybe the experimental MegaTune doesn't yet reflect all iac related config changes, or simply misconfigured. Or maybe there is a firmware bug in the experimental release (unlikely). ---- I need another IAT calibration for my newly installed 1.0.36. Marcell did it for my 1.0.30,because of some Windows issues i was unable to copypaste the good airdensity datas.As far as i know airden_3000_287 is what works fine for me. Currently It reads 7-8deg less then real.
