Hey guys im finally will be ready this weekend for a drive around the block in my single turbo build and was wondering if anyone could give me suggestions on SA table and any changes i need to make before the first test drive. I had a pretty good tune before the turbo and she fired up nice and easy (never went into closed loop). Any suggestions would be great thanks BTW its the EBL P4, i have a 7 LB spring and dont plan on running more than that for right now.

Need more details as far as your set up is concern, but if your tune was pretty good NA just about anything UNDER 100 Kpa should be safe enough to take a cruise around the block. Do not worry about the timing under 100 Kpa because you are not in boost. But anything OVER 100 Kpa EBL will command to start pulling timing based off the BST -Boost Spark Retard (2-Bar) table and that timing is being pulled from your SA -Main Spark Table, so do not make any timing adjustments from that table EBL is doing that for you. A good rule of thumb for setting up BST -Boost Spark Retard (2-Bar) table is for every 1lbs. of boost, retard the timing by 1.5 to 2 degrees, again this is just a safe starting point for your timing because every set up response differently. As a matter of fact, if I were you I would start with the lowest boost setting on the waste gate to start with, so remove that 7lbs. spring for now and then go up from there as you get more comfortable with using the boost features that EBL has to offer. It is very user friendly. As far as the vehicle not going into closed loop at idle, you need to change your Closed Loop - O2 Upper/Lower stay in Closed Loop and Closed Loop - O2 Upper/Lower Go into Closed Loop tables. Good luck, I'll help as much as I can.

Yup if tune was good before leave it. Then pull 1-2 deg per lb boost depending on fuel type and compression, and hopefully you run a spark plug thats 1-2 steps colder than stock heat range. I like a ngk 6 on mild motors. 7 for abit more boost and 8 is what i run, 30 psi stuff.

Just walk into throttle slowly and get turbo to start going into boost slowly. Keep an eye on things like knock and air fuel ratio as it approaches pressure. Work your way further into throttle and boost. Wont be long before you are goin wot

good stuff thank you guys very much. And sorry for not listing detail i was just making sure i didn't have to enable anything on the EBL for it to retard boost beside the table its self. I made sure that my boost spark retard table was in place and set conservative for this test run. more details on the build...

Make sure you go into your Constant Flags and set it for 2-Bar Map otherwise it will not use any of the 2-Bar BST tables. I'm sorry I thought you already changed your settings for a 2-Bar.

Do you even have a 2-Bar map sensor?

1992Vortec

Ya I defiantly have a 2 bar map. Awesome I will be sure and set that when I get home

I would start with 2* retard per PSI, and do a 1.2 mult on the injector BPW.

The spark gets interesting if you have PE Mode non-zero.

It will basically 1/2 the fuel if you install a 2bar map, but have the ECM set to a 1 bar.

How does the ECM do rev limiting? If it does cheesy fuel cut then I would remove that all together. You don't want to go lean under boost and break pistons.

1992Vortec

It does both spark and fuel limiting cut i have both disabled at the time for that reason. Awesome ill set the table pulling 2 per LB of boost. Forgot to mention that the compression is 9.4:1.

You are aware that he is using EBL right? So if is using a 2-Bar then he needs to check the 2-bar flag for sure. I've never had any fueling issues when I set that flag.

OP please do what I said, you will not have any fueling issues. If we just confused the hell out you give Rbob a call or just email him your questions at Dynamicefi.com

1992Vortec

ya i seen that he was suggesting terms used on a different management system. But im not confused just was looking for specifics like the very important one you told about setting the flag for the 2 bar, starting points on spark retard, range on plugs and what not all great info tho and will make my first run a lot better. Also saved me from posting a tread "EBL not retarding timing during boost" because i didnt check one box lol

1992Vortec

As luck would have it right before up loading the new tune my hard drive crashed in the computer... but i was able to let it warm up and check for leaks and what not and even better than a turbo is good cooling fans. I can actually control engine temp! haha fought with that for sometime now and a pair of intrepid fans drops the temp quickly.

What I posted is correct. It applies to any ECM regardless of manufacturer/modifier that is set for 1 Bar, but the user installs a 2 bar sensor. That is, the case where the user incorrectly sets the ECM for the given installed sensor.

Well, unless the ECM "auto-detects" which map sensor is installed.........which it could but no manufacturer/modifier does this that I know of.

Pull hard drive and put it in a plastic bag in the freezer. Once cold, install quickly in computer and try to recover the more important data first.

1992Vortec

A buddy of mine was able to recover all the info off the hard drive and give me a new hard drive so my up and running but it decided to go from 75 degrees outside to 3 inches of snow in a day... gotta love Colorado weather lol

I just re-read your original post and noticed that I replied to fast. I guess it was the way it was typed because you touched on 4 different topics with very short sentences. Sorry, I just didn't want to confuse the OP.

Glad to hear you were able to recover your hard drive, but sad to hear it's snowing now.

Funny story 3inches this am now 55 and sunny lol street mostly dry drove her around the block and the last 5 months all make sense now! Torque torque torque. She pulls hard at half throttle no knock and running 12 to 1. Need to muffler tho had a few people a bit mad haha
