Dadoulis Paschalis Posted March 17, 2008 Report Posted March 17, 2008 Hi all!! One little problem came up with the above engine when setup a LEM G3!! This type of engine is originally with Distributor but we've made a modification to this and we changed this with a Corolla/Avensis trigger setup Multitooth 36 Missing 2 !! So our problem is following: The car starts just fine and everything is working smoothly and nice till 4500 rpm!! Pclink shows everything working correctly, till that point signals from rpm sensor and all other sensors like trigger sensor, trigger errors stay at 0 or 1, but as soon as we are at 4500 rpm and over, it starts doing some "crazy" things, rpm getting crazy, does like having fully wrong ignition map, (of course it doesn't)!! TPS is calibrated ok and functions correctly and maps are ok!! Any ideas? Shall I change the whole triggering setup with the old stock distributor setup so as to be sure that it is not the reason?? Forgot to tell that we are running on MSD ignition if any problem with this please let me know!! Any help appreciated!! Thanks a lot for your time! Quote
Simon Posted March 17, 2008 Report Posted March 17, 2008 The first area to look at will be the arming voltages in your trigger menus. You might need to lower these from about 4000RPM and up. Also try reducing your filter levels on trigger 1 to level 2 or 1 if they are not currently. MSD ignition is good for making lots of electrical noise so the running of shielded wires for your triggers will be a must. Simon Quote
Dadoulis Paschalis Posted March 17, 2008 Author Report Posted March 17, 2008 I'll try this for now and I'll let you know my news!! Thanks a lot for your quick response!! Quote
Dadoulis Paschalis Posted March 18, 2008 Author Report Posted March 18, 2008 OK!!! Fixed!! Can you please give me a regular trigger offset for this setup? 'Cause the whole problem was this offset after all!! What is the stock trigger offset for an AVENSIS or CARINA 4A not distributed engine? Thanks!! Quote
Kurt Nelsen Posted March 20, 2008 Report Posted March 20, 2008 Dadoulis, I am undergoing my 20valve blacktop turbo aswell. WOuld you have a basemap you could send me and also i assume you ran the quad throttle set-up? WHere did you take your MAP reading from as they have a very weak vacuum? Please any help will be great here is my email... [email protected] Cheers Kurt Quote
ashesman Posted March 24, 2008 Report Posted March 24, 2008 Kurt: Remeber to use 4D fuel mapping on a multi throttle engine to get around the weak vacuum signal... Dadoulis: We do not keep a database of trigger offsets, these are easily determined using a timing light. Refer to the PCLink help for more info... Quote
