skylinedriver59 Posted October 19, 2011 Share Posted October 19, 2011 I want to know if any has any MS2 maps they can share for my set up. Im running MS-II PCBv3 My set up is Stock L28et with P90 head and N42 manifold -T3/T4 hybrid turbo -MSD 2225 electric fuel pump -upgraded fuel rail -240sx TB -Arizona Z TB spacer -CX racing FMIC -3 inch exhaust -Stock distributor with Z31 module -injectors are 450cc at 38psi, 480cc at 43.5psi (3bar)or 500cc at 47psi I have some files from the map sharing post or other old post (like metro's, raven's and ninner's)but seems like all the maps are for MS1 Im thinking of using ninner's but he has MSD 6al witch might be the only difference. any help would be appreciated, Its about time to get my Z running and driving. Thanks guys! Quote Link to comment Share on other sites More sharing options...
CamH Posted October 19, 2011 Share Posted October 19, 2011 Do you have a wideband O2 sensor? If so, it's pretty easy to tune yourself using TunerStudio. Quote Link to comment Share on other sites More sharing options...
skylinedriver59 Posted October 20, 2011 Author Share Posted October 20, 2011 unfortunetly I dont have a wideband. Im building on a budget and I think I just about squeezed every penny on this project for now. I need to fix the Tranny on my TT its kind of a priority since I actually drive it to meets, carshows and the track. after I take care of that then I can caugh up the money for a wideband. Any suggestions, advise or help would really be appreciated. Quote Link to comment Share on other sites More sharing options...
dexter72 Posted October 20, 2011 Share Posted October 20, 2011 Just copy a VE and Spark map that is close to your setup and get it running. For the Spark map, take 5 degrees out of it Above 2500rpm, and start things off from there. If you don't have a wideband your going to have to tune it while driving. Charge your laptop battery, fill it up with fuel, and bring someone with you to change the VE bins and don't mash the gas pedal. Start off with easy acceleration runs. Save all the changes before your laptop battery goes too low. You will be doing this all weekend. ) Enjoy Quote Link to comment Share on other sites More sharing options...
CamH Posted October 20, 2011 Share Posted October 20, 2011 I wouldn't street tune without a wideband. Take it somewhere with a dyno and have it professionally tuned if you don't have a wideband Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted October 20, 2011 Share Posted October 20, 2011 No wideband....makes it real tough to tune, and real easy to blow up your engine. Quote Link to comment Share on other sites More sharing options...
skylinedriver59 Posted October 21, 2011 Author Share Posted October 21, 2011 If I don't have the money for a wideband I definitely don't have money for a dyne tune. Well it seems like ima need to get a wideband. What's a good cheap wideband I can buy? Any body knOw or have a wideband I can get for a good price?

CamH Posted October 21, 2011 Share Posted October 21, 2011 I run an Innovate LC1, as do many others here. I think AEM makes another popular one. Quote Link to comment Share on other sites More sharing options...
skylinedriver59 Posted October 21, 2011 Author Share Posted October 21, 2011 ok im going to buy the innovated LC-1 wideband is there anything i should be looking at before I buy? Are they all the same something like a universal fit? After I buy the wideband do I also need to buy the full version of tunerstudio? What are the benefits of buying it?

CamH Posted October 21, 2011 Share Posted October 21, 2011 The benefit of buying the full version of tunerstudio is: VE Analyze Live. This will allow you to make an AFR table, where you want your AFRs to be throughout your RPM/Manifold Pressure range, and then turn on VE Analyze Live and it will basically tune itself.

skylinedriver59 Posted October 21, 2011 Author Share Posted October 21, 2011 I guess im going to buy tunerstudio and a wideband! Quote Link to comment Share on other sites More sharing options...

skylinedriver59 Posted October 22, 2011 Author Share Posted October 22, 2011 Ok I just ordered my innovate LC-1 wideband as well as payed for tunerdtudio. Thank GOD for credit cards lol! SO Tunerstudio MS pretty much tunes the VE table right? How about spark? I know there's a write up on tuning with megatune, Is there an up to date write up on how to tune using tunerstudio?

Zmanco Posted October 24, 2011 Share Posted October 24, 2011 (edited) My setup is pretty similar to yours (same turbo, LC1 O2 sensor, 437 cc/min injectors, but Isky turbo cam probably is different) so I'll attach 4 tables that can help you get started. The first three, VE, AFR, and Ignition are pretty obvious. The fourth is needed for the VE Analyze Live feature. Basically this tells TS how much delay there is between a combustion event and when those exhaust gasses reach the O2 sensor. By trial and error I've arrived at this chart. My O2 sensor is mounted on the underside of the downtube near the bottom to get it away from the hot turbo. If you've got the sensor closer, you may need to shorten these times. A note on the VE table: Req fuel is 7 ms for my setup, but I run with half that (3.5 ms) which doubles all the values in the VE table making it easier to tune at low pulse widths such as idle. You will need to scale the table to whatever Req fuel you choose to run. Edit: Since all the VE values are 2x, you should enter half your calculated Req fuel in the top box. Another note: before you spend much time tuning, make sure you load the correct injector dead time. changing this later will change the entire VE table, especially for cells with smaller VE values where dead time is a large portion of the total injector PW. If you don't know what the dead time is, read the manual for MS/Extra where it explains how it works and gives recommendations for low and high impedance. If you want to measure it yourself but don't have an oscilloscope with current probe (who does?) you can follow this method. Get the idle tuned so it's stable, both rpm and AFR. Then alternate between 2 and 6 alternating squirts. When you have the correct dead time, the AFR will be the same for both. Be careful of heat soak of the IAT - I'd recommend doing this on a cool day with the hood open. Once you have the dead time set, you can use the VE Analyze Live feature to autotune while you drive. It works amazing well - assuming you have reasonable values for Lambda Delay. Otherwise you'll see some strange changes in the lower half of the VE table, especially in the lower left corner. And one more word of caution - be careful about running much boost until you know you have everything sorted. It won't take much detonation at high boost to break something. I highly recommend running a knock sensor, such as Knocksense. Even if you don't integrate with MS, it will flash an LED whenever it detects detonation. Including the sensor it's about $100. Consider it cheap insurance. Daniel's MS tables 2011-10-24.zip Edited October 25, 2011 by Zmanco Quote Link to comment Share on other sites More sharing options...
skylinedriver59 Posted October 25, 2011 Author Share Posted October 25, 2011 Thanks for the help Daniel, I really appreciate it but How do I view the files? lol Quote Link to comment Share on other sites More sharing options...
Zmanco Posted October 25, 2011 Share Posted October 25, 2011 Within TS you can import and export tables. For example, open the VE table and look at the green arrows on the top row. Hover the mouse over them and they will tell you which is import and export. Use the import function to load the VE table I provided. You can do the same for the others too. Note: I corrected the instructions above for Req fuel. Use the calculator in TS to determine Req fuel and then divide by 2 and you can use the VE table as-is.

skylinedriver59 Posted October 25, 2011 Author Share Posted October 25, 2011 Ok thanks I couldn't figure it out last night maybe cause It was late and I was tired. I checked them out this morning but I dont know when ill get a chance to work on my car. On the injector dead time is that only calculated according to megasquirt. Or can that be calculated on a injector test machine Quote Link to comment Share on other sites More sharing options...
