Guest |216| Posted September 3, 2010 Report Share Posted September 3, 2010 Is it possible to use the V88 with an odd fire V10: Bmw s85b50. The engine fires like this: 0,90,144,234,288,378,432,522,576,666. The "waste cylinder" will be 18 degrees before/after tdc when it fires so that should okay??

rayhall Posted September 3, 2010 Report Share Posted September 3, 2010 Ten cylinder odd fire engines using wasted spark are supported by the V88. There will be no problems with this engines cylinder locations Ray. Quote Link to comment Share on other sites More sharing options...
Guest |216| Posted September 3, 2010 Report Share Posted September 3, 2010 Okay great. Are there any plans for Vanos (vvt) support for this engine? Quote Link to comment Share on other sites More sharing options...
rayhall Posted September 3, 2010 Report Share Posted September 3, 2010 How many teeth are there on each cam. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |216| Posted September 3, 2010 Report Share Posted September 3, 2010 It has 6 teeth on each camshaft with different size and space between. Quote Link to comment Share on other sites More sharing options...
rayhall Posted September 3, 2010 Report Share Posted September 3, 2010 That is odd for a BMW engine. They nomanly have 6 teeth on the inlet cam and 7 on the exhaust. I am going to need a drawing of the teeth on the cams and the position of each. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |216| Posted September 5, 2010 Report Share Posted September 5, 2010 Is it possible to get the needed positions using the "Cam Angle Test" function? If I first do it with falling edge and then with rising edge Shouldent I get the size/position then?? I am not to keen on disasembling the camshafts to try to measure them.

rayhall Posted September 5, 2010 Report Share Posted September 5, 2010 To do the cam test you need to make the engine run. The test will then give values we can use to decide how you setup an existing BMW VVT trigger or if we need to add another. For the engine to run it needs the cam signal. But this is only the case in 50% of starts. You can select Sync Mode = None. Select BMW Dual Vanos as the VVT pattern. Crank the engine if it will not start try again and again. When running set the ignition offset so the ignition timing is correct. Select Cam angle test and set the number of teeth to 8 Do all four tests (Inlet LH, Inlet RH, Exhaust LH, Exhaust RH) Press the R key to view the runtime data. Select the VVT tab. The Absolute VVT Positions will display the cam tooth positions in crank shaft degrees. Do not worry is some values repeat. Either save the map during the tests or take screen shots of the runtime data and email it to me. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |216| Posted September 5, 2010 Report Share Posted September 5, 2010 Ok thanks for the info. It will be a while before it`s up and running. But when it is I will contact you. Eivind. Quote Link to comment Share on other sites More sharing options...
Guest |646| Posted September 6, 2010 Report Share Posted September 6, 2010 This is a great project! Once it's up and running will be the best proof of the power and potential ViPEC has for running sophisticated engine management. This is maybe one of the most complicated mass production engines by now. Just out of curiousity as a BMW fan - What gearbox will you use and in what vehicle? Also how would quad Vanos be connected? 8 outputs for 4 cams x 2 directions (advance & retard)? Or Both inlet and both exhaust cam will be connected in parallel? As far i've seen on the internet only MoTEC and Pectel successfully implemented on this engine. Quote Link to comment Share on other sites More sharing options...

Trigger 1 = Crank trigger signal Trigger 2 = Exhaust cam LH Digital 1 = Inlet cam LH Digital 2 = Exhaust cam RH Digital 3 = Inlet cam RH Aux 1 = Inlet cam LH Retard Aux 2 = Inlet cam LH Advance Aux 3 = Inlet cam RH Retard Aux 4 = Inlet cam RH Advance Aux 5 = Exhaust cam LH Retard Aux 6 = Exhaust cam LH Advance Aux 7 = Exhaust cam RH Retard Aux 8 = Exhaust cam RH Advance The diodes in the VANOS solenoids must be removed.

Guest |646| Posted September 7, 2010 Report Share Posted September 7, 2010 Now I understand what LH and RH mean. Maybe Left Head and Right Head when using in V motors.. Quote Link to comment Share on other sites More sharing options...
rayhall Posted September 7, 2010 Report Share Posted September 7, 2010 LH = Left Hand RH = Right Hand Your translation also works.... Quote Link to comment Share on other sites More sharing options...
Guest |216| Posted October 11, 2010 Report Share Posted October 11, 2010 Just out of curiousity as a BMW fan - What gearbox will you use and in what vehicle? .

Ray. Hi Ray. This engine is a bit different from the other Vanos engines, it has only 1 solenoid pr camshaft, they return mechanicly to their base position. So how should I wire this??

rayhall Posted October 12, 2010 Report Share Posted October 12, 2010 That is like a "normal" VVT control. Aux 1 = Inlet cam LH Aux 2 = Exhaust cam LH Aux 3 = Inlet cam RH Aux 4 = Exhaust cam RH Ray. Quote Link to comment Share on other sites More sharing options...

Guest |216| Posted March 23, 2011 Report Share Posted March 23, 2011 Ray. Will the trigger pattern for this engine (bmw s85) be added in the April update? Quote Link to comment Share on other sites More sharing options...

Guest |216| Posted May 26, 2011 Report Share Posted May 26, 2011 Ray. Finaly home for some testing for myself, like I said in the Email I sent you there is a trigger error on the LH exh cam, shows error on 2nd tooth. This is due to a error done by me under the logging. But there is a bigger problem, the Odd-fire does not seem to work.. The engine always fire in the same place. I set the timing to 12degrees btdc over a large part of the timing table (in case the lock timing disabled the Odd-fire) and checked with the timing gun and the timing were rock stable. Shouldent this jump back and forth because of the 18degree odd timing on the engine? on a positive note the Inlet vanos seems to work fine did a quick test and they moved around . Did not test the exhaust because of the trigger error. Eivind. Quote Link to comment Share on other sites More sharing options...
ashesman Posted May 26, 2011 Report Share Posted May 26, 2011 The timing should be stable with the timing light. You must be using wasted spark. The two cylinders wired together will (should) have the same TDC angle. So, the timing light will flash once per crank revolution in the same place. To test the odd fire, you need to mark the TDC of each cylinder on the crank pulley. Then put the timing light on each HT lead and check it is flashing in the right place for each cylinder. As for the exhaust cam, I have altered the trigger decoding pattern and will send some firmware hopefully later today.

Guest |216| Posted May 29, 2011 Report Share Posted May 29, 2011 The problem is that the paired cylinders do not have the same TDC. Coil 1 is wired to cylinder 1 which is 0TDC and coil 7 which is on top at 18ATDC and so on.. This quote contains the firing order/the thread start: Is it possible to use the V88 with an odd fire V10: Bmw s85b50. The engine fires like this: 0,90,144,234,288,378,432,522,576,666. The "waste cylinder" will be 18 degrees before/after tdc when it fires, will that be okay?? Eivind Quote Link to comment Share on other sites More sharing options...
FIS Posted May 21, 2012 Report Share Posted May 21, 2012 I have V10 engine with firing order 0,90,144,234,288,378,432,522,576,666, with latest firmware 4,9,1 does V88 can run odd fire wasted spark? Quote Link to comment Share on other sites More sharing options...
Simon Posted May 21, 2012 Report Share Posted May 21, 2012 There is no way to run odd fire wasted spark on any of our ECU's :cry: Currently the only way would be to go with 2 ECUs and run full sequential. Quote Link to comment Share on other sites More sharing options...
