Roman Posted January 18, 2018 Share Posted January 18, 2018 Ugh yeah i pulled hilux engine out when i was down at HPA, not sure if it was a 1kd? Cant remember. Was running a prototype diesel ECU from motec. With too much boost towing the race car back to HQ from highlands it split a piston. The oil coming tgrough the split kept combusting and nanged the engine at max revs haha. Intake looked amazingly disgusting. 3 Quote Link to comment Share on other sites More sharing options...
kws Posted January 18, 2018 Share Posted January 18, 2018 Yeah the previous gen mitsi triton was terrible for egr carbon in the intake. Used to be two cans of shumma intake cleaner, a can of brake clean and a couple hours labour to fix. Quote Link to comment Share on other sites More sharing options...

ajg193 Posted February 2, 2018 Share Posted February 2, 2018 If I were to use ECU controlled ignition, would I get away with just putting the spark through the distributor and assuming that my programmed advance curve will fall within the tolerance of the distributor's curve? I.e. how much misalignment between the rotor and the posts is required before you will get a missfire? Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 2, 2018 Share Posted February 2, 2018 As long as the dizzy is still timed correctly you'll be fine. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted February 2, 2018 Author Share Posted February 2, 2018 And disconnect the Vac advance line? Weights etc? Or remove the dizzy, blank the hole, run direct ignition for a cleaner setup and one less gap to jump Quote Link to comment Share on other sites More sharing options...
ajg193 Posted February 2, 2018 Share Posted February 2, 2018 Leaving vac and weights on will let the distributor approximate the curve more closely than if it was just a locked out distributor. This way I can just run the single coil and keep essentially factory looking system, apart from an ugly trigger wheel on crankshaft. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 2, 2018 Share Posted February 2, 2018 Nope. Lock the dizzy, do timing with ECU. However if your pickup is from the crank and no longer from the dizzy, it won't actually matter if you lock it or not as it's trigger is being ignored. In any case, the Ecu controls the timing.

Yowzer Posted February 2, 2018 Share Posted February 2, 2018 The advance mechanism in the dizzy doesn't alter the rotors position in relation to the cap, it only alterers the ignition trigger. You could rip it all out quite happily. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted February 2, 2018 Share Posted February 2, 2018 I thought the rotor gets moved with the mechanical advance, and trigger gets moved by vacuum? Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 2, 2018 Share Posted February 2, 2018 Nope, rotor is mounted solid to the shaft. Both mech and vac act on the trigger pickup Quote Link to comment Share on other sites More sharing options...

Yowzer Posted February 2, 2018 Share Posted February 2, 2018 No shit. Shows how long it's been since I've played with mechanical Dizzy's. Ah well, as you were Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 2, 2018 Share Posted February 2, 2018 Sorry I forgot they had those tiny rotor ends, so you could lock it and find a wider ended rotor that fits, or leave it as is but that will limit your range of advance to within the mechanisms of the dizzy. Probably not a big issue tbh but as per your original post, you don't want the spark falling off the end. Your question makes a lot more sense now that I've had a look at a mech 5M dizzy haha Quote Link to comment Share on other sites More sharing options...
ajg193 Posted February 2, 2018 Share Posted February 2, 2018 I think it might be alright with keeping current rotor on it as with the vacuum advance it goes right up past 45 degrees advance without missing, where the vacuum only moves the pickup for the signal. What sort of maximum advance are you guys running with your efi systems? Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted February 3, 2018 Author Share Posted February 3, 2018 I was running a pretty safe 40 advance on V6. If it were me I'd remove your dizzy and run a coil pack. You're so close, but not quite there, to having a really efficient setup. I Dont think anyone will cry if they lift your bonnet and cant see an ugly dizzy sitting there. You can always put it all back to factory if you needed. I'm guessing you need something in the hole to drive the oil pump though? Or does the dizzy drive off the oil pump? I know nothing about these engines. 2 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted February 3, 2018 Share Posted February 3, 2018 Distributor drives pump. I'll cry if no distributor. One crank wheel + sensor = far cheaper than coil packs Quote Link to comment Share on other sites More sharing options...

I know nothing about these engines. Hey Alex. Hope your well mate. Could you help me with a question? Iv always wondered with crank triggers how do you dial the crank reluctor and sensor in spot on? To run a coil pack set up or injectors for that matter. I understand the concept but lets assume that nothing in the world is perfect and you engineer a bracket that makes the sensor sit 1/2 a degree out from TDC. To get things dead on is there a calabration or a offset in the software to correct this ? Hope that makes sense. cheers Scott. Quote Link to comment Share on other sites More sharing options...
Roman Posted February 3, 2018 Share Posted February 3, 2018 There's an offset in the ECU, and you set it up with a timing light. You dont need to have the angle exactly right. Quote Link to comment Share on other sites More sharing options...
