I set the timing by feel on the RB25DET - It has knock sensors and if it detects knocking, it immediately retards the timing off, quite dramatically, you feel the car tugging under power. An electronic ignition timing system which cooperates with an adaptive closed loop fuel control system to provide more rapid heating of an exhaust catalyst by retarding the ignition tinning during colds starts only after an index of maturity value has been generated to indicate that fuel control parameters which characterize an individual engine have been adaptively learned and are available. php on line 143 Deprecated: Function create_function() is deprecated. PROCEDURE Step One Determine the base line of the settings that affect timing and write them down. Dynamic Timing is checked with a strobe timing light, engine running preferably in a test tank. Even though your engine may be antique, that doesn't mean it can't be a great performer. Rotate the cam on the AAU clockwise against the springs. If the RED mark is not lined up then it is not set right. This is an AUTO TRANS. In addition to checking ignition timing, you can also use the digital display to advance or retard timing from 0-90 degrees, and check tachometer, voltage, and dwell readings. • In the BigComm Software (Operating Configuration), set the crank reference setting to 50. 05 degrees for steady-state and transient testing. It shouldn’t take much rpm to peg out the advance without the springs installed. Are there any suggestions for atleast sorta setting my timing for good gas mileage. EDIT : The timing light is a bright strobe light that only flashes when your spark plug ignites. If you don't have a ohmmeter, set the engine on the compression stroke, then remove the distributor cap and put some cellophane from a pack of cigarettes between the points. Ignition Timing Light Gun Construction Plans Elmer Verberg's Vertical Wobbler: Elmer's vertical wobbler engine is a two cylinder inverted "wobbler" style where the motion of the cylinders automatically operates the valves. An auxiliary engine ignition timing display tool for use with a strobe timing light in setting the ignition timing of a Harley Davidson™-type motorcycle engine, the engine having an indicator for ignition timing viewable on a timing indicator side of the engine and an engine ignition timing setting adjustment device accessible on a timing adjustment side of the engine. Rotate the stator and tighten. 020 and now I intend to set ignition timing by using a neon timing light, but I don`t know how to do it right. Timing lights are a diagnostic tool used on cars without computer-controlled ignition to help the mechanic find the correct setting for ignition timing. The timing is set by using a dial test indicator as described in the manual. Timing is everything, and without a proper timing curve, every thing else goes out the window. ACCURACY IS VERY WANT TO BUY. Hi All, Ive just got my TR6 back on the road after 16 years (the last 3 years doing a full body off rebuild). The timing tape is also useful for setting the total timing and for setting up a performance timing curve for the ignition, without needing a dial back timing light. This product is definitely the best timing light for msd ignition that allows you to enjoy its excellent performance. Really useful little piece of equipment. if i moved the dizzy &. Just to recap - Synchronizing the EFI timing (laptop) with the engine timing (timing light):. If you have very well insulated spark plug wires the timing light may not sense the signal thru the wire. Now rev the engine just a little while observing the timing marks with the light. The authors have been discussing this subject for some time, each approaching the project with differing objectives. It is set when the engine is built, aligning them to. I do not have a timing light in order to set it to 6 degrees, and I have no money to buy one and I don't know anyone who has one. However you achive this is your problem. With the SRM/Boyer or Crank Triggered Boyer electronic ignition it's imperative you check timing with a properly calibrated degree wheel on the crank and a electronic timing light. Part 2: confirming the timing belt timing 1) Find ignition TDC for cylinder #1. "There is a time for peace and talk and reason; and then, at long last, and only with sadness of heart and mournful admission that all your wisdom and words have failed, you must go kill you some motherfuckers and set some of their shit on fire". The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
