  1. Here is the last dyno run we did to tune the car. It is a blast to drive. There are 29 pulls on this zip drive. You can just look at the last 3-4 pulls as they are the final tune. 225hp with 255 tq on the dyno. Think I am conservative enough on tune for longevity. Still need to work on decel, and initial tip in. Had multiple issues to deal with at the dyno. Kept losing power to the TPS(was the connection being loose on the spade to fuse panel). Blew coupler off did not know it for first 10 pulls. Pulled the power to 3 injectors by accident while closing the gaps on spark plugs. H
  2. Reading at 0 throttle is 220 and at full throttle is 1238. Is that correct? Keep losing signal, have traced it through a spade connector that was loose. Once I have reset the signals is as above readings. Throttle application seems accelerated, as in 1/3 is half.
  3. Hello all. So I recently picked up a new 1976 280Z Non CA. It has a few mods to it. Stage III schneider cam, headers, monza exhaust. Something failed on the EFI and the previous owner cracked open the AFM and tweaked a bit. This is causing the engine to run extremely rich. The coolant temp sensor is dead also. I've decided after seeing many split wires and splicing that it would be best to start new with Megasquirt. I plan on purchasing the MS2 3.57 assembled unit and wiring harness. I know this question strays from the normal. I know the option of going to a 82-83 dizzy. As of right no
  4. I have been trying to get my 280z running again. I moved and changed jobs so it's been a while but finally getting back into it. I check all my wiring again and everything seems to be right. So I figured that I would check the board to make sure the jumpers were in the right place(I bought the car with the MS2 half ass installed and the wiring was shot). Anyways this is what I found. I am not sure if it will still work or not. It boots and lets me upload msqs to it and it does try to start. Also does anyone have the stock ignition and other setting I need to getting it running? I am using a 83
  5. So it took me one afternoon to rip out the stock injection and get the car wired up and started on ms, it's taken me almost three months since to get things to where I'm pretty happy (one month delay thanks to the stock T3 blowing to bits). My car: 83 l28et, p90a head, stock block with at least 206k miles. Last time I tested I had low compression on #6 (110 vs. 145 on rest). My compression tester was stolen along with my truck and I haven't replaced it yet. I think I might have blown the ring back into place while letting VEAL tune the upper regions of my ve table whilst doing 3,500
  6. Hi guys, I want to know if any has any MS2 MSQ or map they can share for my new setup. Im running MS-II PCBv3 4 bar MAPDADDY My set up is build L28et with P90 head and N42 manifold L28ET bored out to 88mm Ratio is at 9:1 Schneider cam 284-70F Head is mildly ported -T3/T4 hybrid turbo -AEM 50-1200 electric fuel pump -upgraded fuel rail -240sx TB -Arizona Z TB spacer -CX racing FMIC -3 inch exhaust -FORD EDIS 36-1 trigger wheel with VR sensor. Still on the Ford Module with Coil on plugs. -injectors are 480cc at 43.5psi (3bar) You guys were such a big help last time so I thought
  7. Help me HybridZ, you're my only hope. First I have an Megasquirt 1 extra (MSnS 1) v3.0 board. No relay. Before trying to connect MSnS with my laptop it was running rich but working. I tried to connect to the 9 pin using a 15 pin adaptor and connecting it that way. After hooking it up I heard a whistling noise like the injectors emptying and saw the fuel rail pressure drop from 40->0. Afterwards I cannot connect to MSnS. I disconnected the laptop and tried to turnover the engine, no fuel pump noise either. I thought I might've blew a fuse, but they're all fine,
  8. Hi, I picked up someone else's headache apparantly, Its running the MSnS and I tried connecting to the 9 port with my laptop (car off), I heard a whistling noise, went to check it out and my fuel pressure went to 0. Next I tried to open up tunerstudio to MSnS, no response. Un connected laptop to MSnS Tried to restart the car and the fuel pumps not working.. Did I fry my megasquirt?
  9. I am about to hook up my o2 sensor and start autotuning. I know the lean cruise around 2300 is rich. I plan on tuning that to what the car will tolerate. car is 77 280z n42/n47 stock. tune is based on gavins tune. I've been told the upper right section is accurate and ideal. I have no idea what to do on the lower left except for my idle 13.2 and cruise2300@55mph in 5th gear. aft.bmp
  10. I have been doing a bunch of reading on the 83 turbo dizzy and megasquirt setups and I just want some verification that it's input voltage is 12v and not 5v reason being is my setup was getting really erratic spark I was wondering if I was feeding the dizzy too much power since there are two different vvalues to use for each voltage My set up is as follows Ms2 v3 Extra code Stock l28 83 dizzy and an msd blaster Dropping resistors for the stock low impedance iinjectors
  11. I would like to know what everybody is running for dwell on their megasquirt direct (single) coil control on thir l-gata z. For example the stock ballasted 280z coil. The " hot" z31 300z coil and various performance coils.
  12. Scoping the interwebs for some information on my new Suzuki F6A Turbo, I ran across a neat replacement distributor which looks head and shoulders above the conventional Mallory Replacement. It's programmable if you want it to be... There's a bunch of YouTube Videos showing it on FairladyZ's and etc... Some nice video showing the old Hitachi Distributor it replaced, and if you understand Japanese, probably some nice technical discussion as well. Sourced from The Netherlands, check it out, jump around the website they have distributors for most anything out there. Flying Magnet by the
  13. Okay guys im totally stumped. The car is a stock 1977 280z with a n47/n42 and stock distributor. I am attempting to megasquirt it v3.0 board msns-e 029y4. I cant get the vr sensor to read rpms or better yet i cant get tuner studio to see rpm while im cranking. I built this board myself, everything looks good. Both trim pots are 18+ turns ccw. Ive wired the vr sensor backwards nothing. The only way to get that rpm gauge to move is to short the sensor and tap the connector together. I dont own a scope but i do have a multimeter. I dont have a stimulator but theres one in the mail, It will be her
  14. So I really hate to do this to my pride.. but I'm not super great at this stuff and I just want to make sure I have my settings and setup "generally" correct so I don't blow my engine or ~$400 ecu investment up. I would greatly appreciate any constructive advise as to what setting are wack or what should be corrected immediately via me being a noob. I honestly went through the the "http://www.megamanual.com/mt29.htm" and did the best I could to follow along but I'm just nervous about my work all I'm asking is to look over my MSQ and give some advise for the parameters I have for my setup I wi
  15. Well here it is, my first build thread on this site. I am looking forward to see what comes out of it. Coming from a 350z, building a 240z is totally different. This is my first time working on a turbo car! I wanted to find a nice platform I can build upon. Here are Pictures: Mod List: ZX F54/p79 w/new Ishino head gasket installed, 160 psi across the board Dished turbo pistons T3/T4 turbo .63 /.60 IC piping in 2.5" and eBay intercooler BOV NA cam N42 non egr intake 440cc Supra injectors Pallnet fuel rail +1 extra 240sx throttle body w
  16. This is the start to what I hope becomes another great build thread. I picture it ending with a photograph of my Z, shining in the beams of Texas sunlight coming through a massive cloud of burnt rubber. There I am in the driver seat… old, broke and happy! I am an engineer, not a mechanic. I hope by the end of this project and after a few more years at my job, the gap between the two will meet somewhere in the middle. I do not have unlimited time and I have a baby on the way, so I apologize in advance for any long periods without updates or if at some point this becomes another sad par
  17. This is our latest standalone engine management: MS3-Pro with 8' wiring harness The MS3-Pro is able to run up to 12 sequential fuel channels and 8 spark channels. This is based on the MS3, but we've made several changes to make this the toughest ECU we can make it. Some are pretty obvious, like the AMPSEAL connectors and O-ringed plastic case. There's several internal improvements as well, other than putting all the optional extras in one compact package. We've got a more detailed list of its features at the link, but here's some of the highlights: - Traction control and slew control - Cl
