Why we removed 2 teeth 180 degrees apart on the 24 trigger become PhatBob recommended this set-up. Next trigger is tooth 6 The trigger and vr is located at the camshaft i.e. distributor driven. * VehicleFitment/Toyota/Triggers Primary trigger Edge = Rising Type= Multitooth Filtering= Disabled Advanced Filtering= Disabled Special N-1= Disabled Fiat Stilo= Disabled TDC after the trigger=127.5 Number of teeth on the wheel=11 Trigger tooth=1 Next trigger tooth=6 Crank min. period= 3000 Tooth width= Angular width of tooth=30 Tooth Relation normal=121 Tooth Relation Missing=181 Phase Angular width of missing tooth=60 Engine phase when to reset=216 ---- This setup is not working very well, with the VEMS,as it cant read the signal proppely, The signal on a scope, looks fine,but it only makes a wave,at 0.5volt,in megatune that will make the rpm gauge jump around, showing sometimes, 50-400 rpm with spikes to 2000rpm,this will make the car backfire and dump fuel into the cylinder,before it stats,so not working well, but ones the car starts , it runs without trooble, i will see if i can get someone to make a amplifier, or something to make the vems able to read the signal, Otherwise it will probbely be replaced by a better ducumented setup. ---- This have now been corrected,and is working with no spikeing at all,i will explain it later,as i think this can be done on alot of the ones that have rpm spikes,it´s now rock solid,this is a build in feature of the lm1815 chip,it have been pulled low, with a solder on two pads,just left of the chip(if you hold the plugs towards yourself)there is 3 pads, and there is made a soldereing between the top two,this is done by a friend that looked at the board for 5min,and then said, that´s it,and it was :D ---- THE CAR STARTED with another Vems ecu,and i found out that the ecu is not working right! * if it's not responding on the VR input signal, the only reason for this (since it's never sent without input-trigger test) is that bad GND and GND5 connection broke the TPIC6A259 (p259) chip and that pulls down the LM1815 (VR-trigger sensing chip) supply disabling it's operation. Make sure that GND and at least 3 (preferrably 4, with EC36pin22) GND5 are always connected preferrably very close to EC36 (max 40cm), and don't have the chance to come apart during operation. Check [http://shop.vems.hu/catalog/index.php?cPath=1 your configuration's pinout in webshop] Verify p259 outputs (eg with mdh commands) GenBoard/Manual/DigitalOut/Table, if the p259 chip was damaged it needs to be removed or replaced. Will check more tommorrow!. '''make sure to publish your used config in Manmcdmct dump format''' to make it easy to reprocude (and eliminate any problem with using unsuitable MegaTune for given firmware, or vemsv3.ini error) -------------------------------------------------------------------------------- Similar engine Can someone provide a pic, were the 2 teeth ae removed from the 24teeth wheel?,or does it not matter what teeth i remove,as long as its 180degees apart? why do you want 2 missing teeth? 1 missing tooth, like 24-1 is much better, especially if you want camsync (and COP) later. The only advantage of 2 missing teeth 180 crankdegrees apart is slighlty faster (1/4 crankrot average vs. 1/2 crankrot) sync at cranking, but Mik (MembersPage/MichaelKristensen) hated his 36-2 (180 crankdeg apart) missing tooth so much he patched one of the missing teeth (which was harder than it seemed). And do i run it VR or Hall? do you hav HALL or VR sensor ? Measure resistance between sensor leads, each pair of pins, both direction, and document it - so we can tell if it's HALL or VR. Scopeshot of the signal also reviels, of course And it would be perfect if i could get the wire color of what wires, that is what, on both the TPS(3 wires) and the the OE trigger sensor(4wires)on the toyota blacktop wiring Thanks. Skassa. MembersPage/PhatBob All the 4age wiring diagrams are here: http://www.club4ag.com/technical_main.htm#4A-GE/GZE%20Specifications%20and%20Data Development of the Toyota 4a-ge installation goes on at a pace: The standard Toyota MAP sensor will work fine with VEMS for NA. The knock frequency for this engine is 7KHz. I am making plug and play looms for 20V engines so if you email me phatbob at www.vems.co.uk with any wire questions I can look at the loom I will be working on tonight and will be able to help with your queries. I am banking on the dual-solanoid IAC thing working as the whole IAC thing has caused the first 20v I did to behave very badly at idle. -------------------------------------------------------------------------------- 07-08-2006 I have now conntected the OE 24 teeth wheel,but the triggersignal is jumping aound from 25-350rpm,so there is something wrong, can somebody help me? probably, start with uploading config (Manmcd, mct dump). Don't forget firmware version, just in case. I run it as VR, and have grinded the tooth,so that next tooth is trigger tdc,and then 180degrees oppesite. 12-1, next trigger tooth 6. Or is it better just to mount a new triggerwheel on the crank? I also need some helt on the injector settings,as this is really bad explained, there needs to be some standard settings!! There are very many examples on MembersPage, consider any working setting as standard setting. Your better explanation is highly welcome, please remember to take a few mins with this after you understand GenBoard/Manual/DigitalOut/Table better. There is a proposal to use the "injgroup" naming during configuration so it's clearly separated from injector outputs (one knows that if he configures injgroup6, injgroup6 must be configured elsewhere regarding what injector output or outputs to contain). -------------------------------------------------------------------------------- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
