Just make sure that your VE table is 100% before you start on AE settings, that is after what ive heard is very crutial. Im about to dial my own in myself. A friend of mine also want a Z car so if you know aboute anyone good thats up for sale, please give me a heads up. My email is: carsmart@gmail.com //Stian

Hi, i had the same problem but i solved it by looing at this video. Make sure you look at the whole video. //Stian

Do you have a good working table for the MAF G35 that you got, perhaps i should buy one of those instead. Or a tune that you kan post. Thanx

well the problem is that the maf voltage dont change when i rev the car. all wiring is ok, the manual have been read 100 times. the car runs fine on map.

Hi, i have tried "again" to get my Nissan Q45 MAF to work with my ms3pro. Im on MAP now but ive heard that the car runs smoother with maf. The car is a Datsun 280z with "81 L28et Turbo engine from nissan. Or should i get a Nissan 350z maf? I have wired it as i "think" it should be according to ms manual. But it wont change the voltage or registrating any airflow, i have read somewhere that i should use a pull up resistor to get any readings. Is that correct? And f so what resistor dio i need to use? Thanx

Do anyone have pictures or info on how i should set up the CAM sensor for sequential fuelling with Megasquirt ms3pro. I dont have any ditributer since i went 36-1 trigger wheel on the crank and wasted spark. Any pictures? Can i use RB25 CAS ? Drill a hole in the valve cover wit magnet glued on the camshaft and a hall sensor. I have heard aboute Kameari adfapter for L28et and Rb25 cas Any ideas

Hi, i have a Megasquirt but i would like to add a Neutral switch sensor as safety switch for remote start, and a VSS sensor for the Megasquirt and aftermarket Speedo. ( do not want GPS speedo) Have anyone done this on this car? If YES how did you do it and what parts was used? Thanx

I mounted my sensor in the cylinder head, its close to cylinder 5-6.

So i have sold my ms2xtra, so im going for either ms3x or ms3pro, but is it really nescesary for me with my motor to buy ms3pro instead of ms3x. One of the reasons why i sold my ms2extra was because i wish full seqential injection and also maybe a better Flex fueling blending tables. Is the setup for ms3x the same as ms3pro or is there any big diffrences there? What aboute blending flex E85 tables the same for the two of those? I have heard someone says that the ms3pro makes the car and idling will be much better than ms3x, is this true? Why would i pay pretty much more $ for ms3pro? what is the big diffrence, remember this is a straight six, 2.8 ltr Turbo. And now the Dollar is pretty high, good for you guys in the US, bad for me in Norway. I will take my time this time and not rush before i buy me a new Megasquirt. All inputs are welcome. Thanx

Really, no one???

Hi again, here i come with some stupid questions "Again" with my L28et, turbo Datsun. I have made 2 tunes one with 2 squirts simult, and 2 squirts Alternating. On the 2 squirt simult. the WUE tuning is "Normal" after used Tune Analyze Live, but on 2 Squirt Alternating the walues goes to 100% all over the board after Tune analyze live. Why is that? Im posting both of the .MSQ the one called "NR2" is simult. 2 squirts, / and Stock.MSQ is the one i would like to use. I bought new injectors before i started, can someone give me the correct Dead time on 13.2V, see the picture added. its only 4 injectors there but this is a six cylinder, they just forgot to send me the last 2 injectors. (I got them now offcourse) The picture wouldnt upload it was to big even tied to .ZIP it down. So im writing the values from the scheme here: Volts: MS: 8 1.049 9 0.947 10 0.846 11 0.764 12 0.682 13 0.616 14 0.550 15 0.484 16 0.418 I tryed to switch the "stock.msq" from 2 squirts to 6 squirts alternate to check if the AFR went Lean or Rich, it went Lean directly and the motor died almost right away. It idles pretty good at 2 squirts alternate. Im also posting my .Msl from startup today, there you can se that i also get "Lost sync error" On the stock.msq i have tried to make two tables with Kp as switching point, Table 1 for cruising and Table 3 for Boost. Its not dynoed yet, but i wont to have all settings ready when i get to the tuner so they dont have to use alot of expensive time to make the settings correct. 1 Hour of tuning here in Norway is like 230-250$ and its not many over here that knows Megasquirt in and out. I do not want to be the one who pays for theyr education to learn MegaSquirt if you follw me. The GM IAC is working pretty good, but the total closing step is 313, have i set the Cranking stepper settings correct? Im not sure i have.. And the last question (for now) im using ms 3.3.2 version, and the ASE Taper time is in Cycles, does this mean one cycle is one turn on the engine? I have seen some other .MSQ have seconds instead. If you count 100 cycles on idle lets say 750RPM how long time in seconds is that? Yeah i know Stupid is stupid does. Thanx alot for all you guys that have plenty info on everything. Does anyone want to make a Remote Tuning Live, and with that i mean i let you have acces to my laptop with 4G thrue internet, and i call over to you with a seperate phone while im in the car while driving. Like when you have live support from example Microsoft. That would be a funny test. I can even pay for the time been used, if you have the skills to do it then, not a garage tuner like me.

I have tryed to upload the msq file but this forum will not allow it, stupid forum. Can only post pictures.

i have tryed to lower the th ve tab, i can force it down, but still that rich. i have tryed everythong ,

Hi, i have just got my car up starting 280z with l28et, 240sx TB, non intercooler, walbro gsl392, Denso 456cc see picture. i have some problems by adjusting the idle so it wont run rich as 9.8 -10.1 AFR it wont pass the emmision control here in Norway. I have tryed to run 2 and 3 squirts simultnouse, but the best result as far as i think is 6 squirts alternating, it felt more snappy on the throttle. Any tips an ideas? i only have the original idle valve on the top of intake, do i have to mount Ford PWM IAC valve. Or can i alter the deadtimes to get leaner idle? This is High imp 11.5 ohm, so i have turned off PW limiting also, right? The deadtime as you see in the picture is 0.616 at 13 volt. Any ideas guys and girls. Thanx

Thats exatly what i was thinking aboute. Great, if you got some drawings i would like a copy of that if possible, It can be sendt to my email. carsmart@gmail.com or stian.sand@swisslog.com Thanx alot.

I now i got a new issue. i went out to my garage today to start up the car but it didnt wont to start. I checked the fuses and the one to the coil was blown. i replaced it and it blew right up when i put the ignition ON. I disconnected the IGN-6 from DIY and it didnt blow up. So i checked the wires and its all ok (i think) will recheck more tomorrow, but i opened the ms-case and when i put on the ignition without coilpack connected only D15 and D16 LED was lighted up but not D14 thats Spark A if i dont remember wrong. should all of the leds be red when ign is on? Or will it only go on when cranking the engine. I brought the whole box to work and asked a college of mine to check it, he is an electrician, im not and he couldn find anything wrong. Another thing is that i cant connect to to tunerstudio after this either. Any ideas, i will try to see if i connect the computer with JimSteam tommorrow also. Any good ideas how to check the coilpack for short circuit? The car was running fine yesterday. Thanx

Hi Guys thanx for all the helpon my other posts, so here is another thing im wondering about, what is the correct setup in the TunerStudio for 280z Turbo "81 L28ET. I loaded in the a setup from Cygnus changed the spark settings and all of that, i took the car out for a ride on Friday an i got it to run pretty good, But i now that it can run a whole lot better. So here is my questions: - Should the "Incorporate AFR target" in general setting be set at off? - I read that since its a turbo car it should only run on Alpha-N on "Primary fuel load" Should it also then be Alpha-N on "Primary Ignition load" ? - I tryed to set the "Time based Accel enrichment" to TPS Based AE but when i trying to give it some throttle it alsmost die unless i do it really slow if i remember right. - I also have set the Boost controll on Open Loop just to get the car running with some boost, anyone got some setups for correct closed loop controll? It seem like im not getting it right with the programming somehow. My internals are: L28Et, Stock P90 Head (Turbo) stock 1981 turbo motor. Wasted spark, Ign6 from DiyAutotune, 36-1 Trigger wheel with VR sensor. 2,5bar map sensor. 240sx Tb, Q45 MAF Nissan maxima ,infinity, New 460CC Denso Here is link to my .MSQ, feel free to make changes. http://www.msextra.com/forums/viewtopic.php?f=134&t=55366 Thanx again to you all.

Thanx for all of the answers, ill leave the stepper issue alone for now, since i get it to idle pretty good without stepper motor. And i now use Fidle for boost control.

Solved!

Here is a link to a simulare one i want to mount. http://www.ebay.com/itm/NEW-IDLE-AIR-CONTROL-VALVE-STEPPER-MOTOR-IAC-FITS-2000-01-FORD-FOCUS-2-0L-DOHC-/400714107784?pt=Motors_Car_Truck_Parts_Accessories&hash=item5d4c6c0b88&vxp=mtr Im just not sure if the holes lines up.

Thanx, i dont think i need the adjustment-board though since im using Megasquirt ms2extra that can control IAC. I would like to have one that i can mount directly to the intake manifold where the Vacuum mushroom sits on the top/middle.

Hi thanx for the answer, yes this is for use with Megasquirt ms2extra system. i thought it was on/off since it only have 2 wires that goes in to it, the bottom of it looks alot like the AC idle up valve i allready have on the intake i was hoping that it was i direct swap. here is a picture of the pwm valve from Ford. http://www.ebay.co.uk/itm/Idle-Air-Control-Valve-FORD-Escort-Fiesta-Mondeo-1-6i-1063996-IAC-/150876440059?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2320efc5fb here is the one i would like to change. Damn, cant upload pictures

Is there anyone who has mounted IAC on 280z intake manifold here? I have a screw in GM Stepper motor that i want to use with my ms2extra setup? I have tryed to search alot on google but no luck, there has to be one that have done this before me. I dont want to use on /off valve but the 4 pin stepper motor to get more control and smoother idle since i have AC and some other stuff that use power. Any ideas?? I was thinking aboute this but way to expensive if i dont know if it will work, this is just the housing that i think will be plug&play on my old AC idle up valve on the intake. http://www.ebay.com/...4873d7f&vxp=mtr here is the valve i i bought in a hurry. http://www.ebay.com/...984.m1439.l2649

Thanx for the reply "Metro" Im firing the coils with 3 BIP373, And IGN-6 Coilpack from DIY. The firing order is fine, the unit was ordered (not by me) from DIY, i didnt solder it myself, exept for the third coil "C". Here is the specs: 240SX TB Ign-6 from DIY 36-1 Trigger wheel from DIY Stock Turbo charger Denso 460cc from Fiveo Walbro 255, GSL-392 Not mounted yet. http://www.msextra.com/doc/general/toothlogexamples.html I Think maybe that the VR sensor is wired backwords, since i get 2. Spikes at the missing tooth, i will try to change that later on today/tomorrow.[/background] It backfires and another question is where the missing tooth should be, Think of it as a clock, my TDC is at 10 o'clock and my VR sensor is almo at the same position since i dont want to have the VR-sensor on the other side where the AC-pump is. where should the the missing tooth be 3-4-5-6-7 o'clock. i can count the tooth myself up to where the VR is when i get that far. [/] Feel free to do any changes in the .msq file, I want to use the MAF Infinity Q45 that i just mounted also, little unsure on how to set this up in a good way since i cant find any values for the MAF.
