  1. Thanks Adam, i will do some tuning today to confirm but that sure looks like the culprit and i should have found it.
  2. i ran closed loop boost control w my V88 from 2013 to 2018. this spring i decided to examine open loop. all fine until i switched back to closed loop. i must have some sort of settings problem as it is set for 238/20 psi and i get no wastegate management. zero W Gate duty cycle. boost is off the spring. i would appreciate some help and include my map. i would be happy to provide the log if necessary but it doesn't fit the file size. thanks and still loving my V88. 1 JULY FLY 11 closed loop.pcl
  3. Hello Adam,

    continuing to love my V88. :).  

    from 2013 forward my boost setup has been closed loop set up on a dyno w my tuner. last fall i decided to do some experimenting w open loop.  did that for a while and decide to go back to open loop. i believe i did everything correctly but went for a drive yesterday and had absolutely no WG duty... zero. boost was off the spring yet i had the boost target at 238 kpa/20 psi.

    i believe all my hardware is top notch and it must be some settings issue although i have done my best to check.

    i have a log from the run and my computer says it is 3.4 M but when i attempt to load it it says the file size is too large. i will attempt to send just the log on a follow on message.

    i do have a few other issues that you could perhaps help with...

    neither my old laptop, HP Pavilion, or my new laptop Dell Inspiron 17, seem to work re the "F" keys. i have always wanted the snake trail but never been able to enable it... F6 and . or ,

    maybe this is a question for a computer guy but there should be able to be a way to redirect the keys away from some other usage?  wud love the snake trail for tuning.

    another issue w both laptops is i can only load two lines of a new fuel table. if i construct a new table from mixture map the computer will disconnect if i try to load it in toto. the best i can do is 2 lines.


    Thank You Adam and have a nice monday.

      follow on log re no wastegate management w my closed loop settings. also, what is triggering the galloping at the end of the log please...

      first message should read i decided to go back to CLOSED LOOP

  4. sure... thanks Adam and JMP. i have five pressure sensors working... fuel, oil, Auxiliary Injection system pressure, exhaust backpressure and boost. since backpressure compares against boost and the majority of people i share my info with think in PSI i will just calculate Diff F P manually.
  5. i have 2 issues. one is my issue ( i am losing static pressure under boost. from 41.2 at static to 39.2 at 18 psi.) the other issue is why i write: my Differential fuel pressure appears to be going the opposite (rising) direction. if the pump, regulator, lines and filter are O K DFP should remain constant. rising DFP under boost points to, often, a restriction in the return line. yet if i just do the math using my boost and fuel pressure i appear to be losing pressure under boost. V88. using AN Volt 4 w Honeywell pressure sensor for fuel pressure i attach a log.// no log, too large... can send a smaller one if necessary at 4:06.667 MGP Psi + 2 tenths of one psi AN V 4 fuel pressure reads 41.4 psi static is 41.2 Fuel Pressure KPA 420 MGP 2 Differential Fuel Pressure reads 410 (doesn't quite match up but that is what it says.... close anyway) at 4:18.134 MGP PSI 18.2 AN V 4 fuel pressure reads 57.4 psi static is 39.2 Fuel Pressure KPA is 574 MGP 125 Diff Fuel Pressure 445 DFP moved from 420 to 445? while calculated using AN V 4 and my map sensor DFP dropped any ideas welcomed. thanks and still love my V88!
  6. THANK YOU SIMON! changing the Knock Gain to "1" re-enabled my readings. i don't recall how it changed from "1" but i now will know where to look if it happens again.
  7. THANK YOU ADAM! i don't know what i did to delete the log view but your new Layout solved my problem. i wish you a wonderful Monday:) do you have any ideas as to why my Knock readings are zero from both sensors? previously they were reading fine. i have two late model Bosch sensors and am of course running Link/Vipec internal. thank you, Howard
  8. i connected my laptop to the V88, turned the key on and did a log. i was able to generate a log and save it to my files. i can generate a Mixture Map and Runtime Values... the only thing not seeming to work is seeing the log on my screen. nothing but blank white space.
  9. Thank you for your reply. i tried to post a jpeg of the screen unsuccessfuly however it is easy to describe. Logging 1 page is entirely blank. no time data, absolutely nothing but white. when i right click on it i get "New View." with a number of options starting w Run Time Value List, which leads to Run Time Value List Properties. other items are Digital Gauge etc. if i go back to Logging and click Play and look over at my Parameter List i see all the data moving but nothing but white on the Logging part of the page. my V88 has worked fine (love it) and this is something that just happened Friday. i have attached a log Log 1-11-17 3;22;45 pm.llg
  10. after working fine until today all i get is white space where my Log Analysis should appear. i believe i have tried just about everything. after clicking on and calling up a specific log in spite of seeing a blank white space i am able to do a Mixture Map and Navigator. the Parameters appear. also, my two Knock Sensors (newer style Bosch 2 rotor motor) stopped generating anything but zeros a couple of days ago. since each stopped at the same time i am concerned that something malfunctioned in my V88. settings have been verified "Internal" would greatly appreciate any suggestions.
  11. thanks to all the respondents. the Toshiba looks like a simple solution. i have a feeling this subject is of significant interest since we all are logging with something. any other replies welcomed. Howard
  12. i have been using my HP Pavillion 17 inch screen laptop for logging/tuning. i want to switch to a smaller 14 or 13 inch screen machine so it will be easier to secure while i am on track at the Texas Mile. technology has marched on and i would like to take advantage of the faster machines. most of the newer Intel powered i7 machines run on a 64 bit architecture. will my V88 work with 64 bit? is there any advantage as far as logging speed with a faster machine? the newer machines offer a 3.0 USB. will the 3.0 work with the V88? any specific recommendations? thanks! Howard
  13. Dave, i second Scott's suggestion re Exhaust Gas Technologies. they offer a wide range of EGT related products that i have used for a number of years. i especially like their line of new voltage conversion modules (amps). they sell into the true professional racing market and offer very competitive pricing. their line of themocouples is broad and i strongly suggest you contact them so that they can build you the exact setup you need. i have no affiliation w them other than being a satisfied customer. excellent guidence from Scott. howard coleman
