  1. Naaa... Thanks for the reply but thats not it. I know of the M key and i use it all the time. That one is for one cell at the time. I belive this mixture map should let you tune multiple cells at once based on the logging you did. It should fill in the logged data for you automaticaly. With the M you need to type what the real AFR was and press enter for it to change the map Now i have not ever seen it mentioned here at the link forum, only over at vipec, so there is a chanse we do not have this option. However i found it mentioned in the helpfile, and the two softwares are much the same (link and vipec) so i belive it should be in there. Just have no clue how to find/enable it ..
  2. that... doesnt make any sense to me at all. Im not afther the main fuel map. But some sort of map that basicly does the same thing as the math key (M). http://www.vi-pec.com/forum/viewtopic.php?f=3&t=479
  3. I know of its existanse and have a good idea of how to use it (from the vipec forum) but i cant for the life of me seem to find it. Of course its not in the help file either. Its mentioned and there is a link, but it leads nowhere.
  4. You can hook it up through the knockblock module.
  5. Cant find anything. If there isnt any, do anyone care to fill me in a bit?
  6. If you are running a MAP sensor,then a big YES! If MAF then no....
  7. Ah. Shait. I missread it. Guess i was hung up at the AIT sensor. No the car was not tuned with fueltemp correction enabled. This is something i turned on later. The sensor sits in its stock location on the fuelrail itself. The numbers put in is just another rule of thumb of mine. So today i turned all my load axis`s to MGP. Still not able to see any Baro correction factor in the runtime values. Should i be able to? What is the logic behind it being enabled in MGP 'mode' and not in MAP? Should i also alter my Fuel equation setting? its at MAP now. Does it need to be set at BAP/MAP Xover? Dont belive i should, but doesnt hurt to ask.. The engine... VG30DETT. Nissan 300zx (z32) Fully built bottom end. Heads ported with 1mm oversize valves. Bigger cams. Bigger Manifolds, exhaust and intercoolers. Turbos BASED on the disco potato (The kit is sold as GT675RS in the Z32 world). Injectors are Nismo 740cc`s (sidefeed). The lag values i got from two different places. Well thats the ruff summary of the engine.
  8. Thanks Dave. No its not particulary hot, maybe 15 degrees hotter than when i tuned those cells. Cant remember really. Had another look at the numbers and its not as bad as it might have looked. Regardless, if you got a map that IS 'better' than the one i got i would love to have it. Of course i could make it myself. Just takes so much more time.. I have not tried to tune with AIT comp off. Doesnt sound like a very good idea either. Also tried to change to Delphi today. It just seemed to adjust it 2 degrees higher. No big difference in other words. Thanks for the heads up on the trans retard I just turned it on at one time with the intention of tuning it when i got around to it. And then forgot as it seemed i did not need it. I zeroed it out at the low cells now and retarded my idle timing 6 degrees. Thats where i want it. About Baro correction. I had the impression that it was always on and running in the background? If no, why not?? There is a place where you select 'normal' or 'marine' sensor. I assumed that was it. I also assume that 100 kpa, or 95 kpa baro is the same in australia as here in europe so there should be ONE correct baro comp map. Yes? If its not on then how do you turn it on? Dont see anything in the software? Do i need to use one of the 'D' maps (4D/5D)? If this is the case then boy do i have a feature request for you guys! If i indeed DO need to use one of my precious D-maps for this (may i state again how that would suck, and how unnessesary it think this would be?) would you do me the honour and send me a copy of one? I have no idea how it should look like. I have not had the car on a dyno since i swapped to the Link ecu. What kind of data would you like to see on a log? Steve
  9. Hi dave. Map attached. The sensor is one i got with my AEM ecu when i ran that POS.. So i guess i can say its a AEM unit. Probably made by bosch or some other vendor though. What do i know... The calibration is copied from my AEM map. Should be correct. Its installed in the pipe just before the throttlebody. The pipe is made of rubber. My issuses is that It was tuned on cooler days than we have right now. And it had flawless AFRs then. Now when its hotter its richer. Its setup running closed loop WB right now. Looked at hte fuel runtime values the other day and i could see my AIT map retracted maybe 2 present fuel. The CLWB however drew about 12 percent from the map. So its clearly not doing very good. Also i dont really understand the values in the 'stock' AIT map. The rule of thumb says that pr 10 degree celcius there should be about 3 percent change in fueling. (well this would dictate a linear map and the real world is not like that. Should really be a parabolic curve. But its a rule of thumb.) The Stock AIT map is not even close to this rule. I actually tried a map looking as how i belive it should look like, but that did not work right. So i dont know what kind of algorithms this ecu runs. Steve
  10. .. than the 'Stock' one in the software? I know someone with a Vipec got one from Ray on request. So maybe you Link people may do the same? Not happy with how it performs right now, and it dont seem to work with a simple 'parabolic' 2D table (for some reason).
  11. Good to hear you are getting closer. Did you try fiddeling with the dither voltage? Did you use a wideband? You want the car to ociliate around 14,7 to help your cats do their work. Exsess fuel-exsess air-exsess fuel-exsess air. This to help feed the cats what they need to work. I have no hands on experience with E85, but i occacionaly hear about people filling a few litres in the tank before testing. So i guess it works.. Dont fill to much though. And dont run it hard. As David here said! Feel free to chime in with suggestions folks. This forum IS somwhat slow, i must say..
  12. I agree. This certainly IS a hell of a lot of fun. And for you, whom built your own car like that, i can imagine the exitement, Reading that you got a smallband lamda setup i think you could leave things in that regard alone. Just adjust the diether voltage to get the apropriate AFR. Thats the only thing its looking for anyways when its set up like that. Adjust the fueling with the CL lambda OFF first. Then adjust the diether with the CL lambda ON so that you get the same AFR. You really should consider installing a wideband (or two). Would be really usefull. Not to say easier for you. As tuning your low load cells with 4 cats on the car would prove quit a task. If tuning with a "but mounted" WB. I somewhat assume your tuner replace one of the lambdas with a WB while tuning though? Your timing map looks very simlar to mine. So it shouldnt be far of. (not saying mine is the perfect one either) Pleace keep me/us updated on this car. would love to se how everything goes. Btw. Saw you over at the Australian 300zx foum too. Not a big poster there, (im mostly at other forums) but i check in regulary to see whats going on there. You know, to get a feel for whats going on in the aussie ZX world.
  13. It does to me... Thats what i would try in that situation. (the "relay on above xxxRPM" idea)
  14. Never mind my VTC Q`s Just re-read your last reply....
  15. That DO look like fun Now i opend the file with the 4.4.3 software version (G4) . so what I am seeing MAY not be the case. Not that it necesarily matters (if it works it probably dont) But the trigger is set up as 1 tooth pr TDC in stead of nissan 360 opto. Any particular reason for this? Your wideband input (AN-1) is setup as 0-5V GP instead of WB input. This way i dont think the ecu knows what,say 2v equates to. If you set it up as a WB you get to choose what 0V meens AFR wise and what 5V meens. You could also set the closed loop mode to WB closed loop. Your "Dither voltage" is set to 0.77v. The ECU thinks that this voltage equals 14,7 AFR. This dont make sense wether you got a wideband lambda nor a smallband lambda. (should be more like approx 0,45v for a SB and around 2,5v for a WB) I think this may be the reason for your failed emmisions test. That said! What lambda setup do you have?? Also in your Target AFR map... Its spanned with RPM over MAP. Good. but here with me the RPM spans from 0 - 983025 RPM. Now this may be cause of my software, dont know. Just check it out. When i go into Injector test in your map i only get injector 1 and 2. What happend to 3,4,5 and 6? Could be the software again... I also see its run as sequensial injection so only 2 injector outputs doesnt compute. Your 400-420 injection timing numbers seem fairly high, yes. But this is best set at a dyno. I got my set at 360 in the VTC off sone and 380 in VTC on. HM. On second look i dont see any VTC output set up. Running without it? If so you are probably loosing some goot power in the midrange. Then again, this may be what your AUX - 5 GP output is used for? The settings certanly looks that way.. About your startup. To me your Warmup map looks good. Dont really see why it wont run right. Look at the wideband numbers while your warming it up and se what it tells you. (But get the WB set up correct first. if thats what you run that is) You could try to play a little with the ECT ignition trim. Ad a few degrees while the engine is cold. What plugs do you run? The engine should only be ran with OEM plugs. Cooler yes, but still OEM. No other plugs really fits theese engines. Have your tried to manualy adjust the idle air screew? Again! I opend up the map with what MAY be the "wrong" software so what i see may not be the case.
  16. A little quick to press "post comment" there... As you said it is a basic tune. How "basic"? Have you i.e. done your warmup enrichment ? Did you calibrate your timing, MAP (if thats what you run), TPS and so on. What timing and so on... Tell you what... Post your map and ill take a look at it if you want. (I run the same engine. In its original home though) What ECU btw?
  17. Nice! looks like a fun car. What ever the rest of it looks like Are you running speed density or MAF setup? Got VTC intact or plain adjustable intake gears? What do you need to get a "pass" on? HC or what? Do tell a little about that setup looks intresting.
  18. I saw over at the Vi-pec forum that the last method they tested wasnt good enough. So ill guess its going to be a while yet. It better be darn good when it finaly appears then...
  19. Yes its a G4 xtreme. (Wire in) Simple really. The main rpm and map limits in the ecu are based on ECT. Wich i said is nice. But as oil heats up slower than coolant it would be nice (vice) to base it on oiltemp instead.
  20. Would be nice to be able to look at the last run even if you did not clear the 10 logs before you made it. Like if something happend while driving it on the street while your were "everyday driving" it would be nice to be able to go back and check your logs.
  21. Yes you could. If you didnt use up the 2 GP limits on other things allready.
  22. ... would be nice. The way its now against ECT is also good but would be better to have the ability to span it against oil temp ..
  23. Ops. Never mind. I missread it... Need a LOW impedance coil for it to vork..
