All your Adaptronic boosted NB's are belong to us
 

For those that don't follow the build threads...

I drove it today!

Drove great. Adaptronic is Rapid Learing mods is pulling down the fuel cells to the target AFR's. It will take a bit of time, but I could drive this to work Monday.

Very civil, no bucking, no going lean, no knock. It's awesome. Still pig rich in boost, but it will come down.

After some gentle driving I did some 4th gear pulls at 8 psi wastegate. No drama, just boost. It's awesome. I'll probably have to go drive it again.

Woo Hoo!

Sweet! Only 104 post over. :giggle:

Guess you're still running the base timing map? That thing sure looked retarded, pun intended. ;)

Oh yeah, you'll be needing one of these soon too.

Cause boost is addictive.

Way to go man, that sure must be nice. I am doing fine on Megasquirt but sometimes i feel like the code could be a bit better, esp with accel enrichments, boost control, idle control, autotuning, etc.

So i bet you are going to be happy with it

I want it bad.

MBC??? Not even. EBC enabled, just need the solenoid. It also has ability to have two maps for two boost levels. Oh, it also has adjustable max boost per gear.:fawk:

After I get fuel decent, it will automatically adjust timing if you enable it to. It records changs up and down in timing per cell against accleration rate and will automatically adjust it for max torque. This does take some time. Days, maybe. It isn't abrupt.

But how do you set it up to know which gear you're in considering we don't have a switch for that stock? Small moment switches around the shifter via the badass short throw that Travis should be building?

I wonder if the taller fulcrum spacer used in the ebay short throws could be remade/modified to incorporate gear switches to be used with the adaptonic. The larger spacer has all kinds of material surface area that can be machined/adapted for switch mounting.

I just jizzed in my pants.
Where do i sign? Seriously.

This beast is using the stock crank and cam sensor right?

Is it closed loop EBC? Be careful with the ECU adjusting timing on the fly. I'd rather do that myself. What if you detonate? And how does it know what gear you're in?

You have to set it up to "learn" that. There is a page where you put in a speed, tell it what gear and have it learn the RPM and speed. It can scale it from there, up and down so it always knows that if you are at X speed at Y rpm what gear you are in. It uses the speed sensors that are already in the car (NB). The same sensors are used for the traction control. No need to buy anything for traction control.

Stock everything. All I did is hook up the GM AIT to the stock AIT, hook the +5V from the MAP to the TPS for 5V (I did that wrong the first time and used the three wires in the MAF) Still using the ground and signal from the MAF. Wire in the WB serially and plug it in. That is absolutely it.

Tune idle (three or four cells) by hand to the WB and then drive and autotune.

Timing adjust at whatever increment that you stipulate, so it can't do something stupid. There is a knock sensor that will also adjust timing. See above for gear. Really simple when you think about it. If it knows one single RPM and speed in each gear it can extraploate the rest.

Got mine in today:)
and then come back after working on the car some more and the map sensor came in as well:D

Glad to hear your car's driving and behaving well....I have a few leaks that made themselves known after turning it on and letting it idle for a bit:mad:

Wow that's cool. Only discrepancy is speedo inaccuracy. My car reads about 9 MPH faster than my GPS. With 205/50r15s and the stock 4.30 gears with the stock speedo sensor. Wonder where the discrepancy comes from, no idea what stock tire diameter is supposed to be.

You guys are all running the 3 bar map sensor right?

As long as it is close and you use the same speedo (duh) it won't matter. You could use a common speed if you wanted to to minimize inaccuracy. Say, let it learn at 40 in every gear.

Yes, we are using the 3 bar GM MAP. Same one as DIY Autotune sells.

Glad to see that you have received everything. I was really lucky (or diligent). Zero leaks or problems. New clutch is sweet. The only thing that I have to do is adjust a muffler hanger as I am getting some rattle on the midpipe to the rear subframe. It's the only part I didn't build as it was already welded to the muffler. Minor issue.

Hey stein is your egr blocked off or are you still using it? also, did you install the check valve in the line going to charcoal canister? what about the primary o2 sensor? I had 2 and left the 2nd one but removed the 1st...... I started the car up today and let it idle for a long time (on stock ecu) and it smokes like a BITCH (black smoke) as well as idle is all over the place. Dont know if its something wrong or because its on stock ecu or whatnot. Hoping once the adaptronic is on and map sensor hooked up at least one of these problems goes away

I blocked off the EGR. Just made a plate and removed the tube.

No installation of a check valve - do I need one? Never saw anything about it in the BEGI installation instructions that I used as a guideline.

I had two bungs in the DP and one in the midpipe, so I am using all three. Stock in the top one, WB right before the cat, stock in the midpipe in the stock rear location.

Probably won't idle for shit with no MAP or MAF as it has no idea how much air is there.

As an aside, I drove it for about half an hour and never threw a CEL in or out of boost.

well i put the maf right before the turbo, same way the voodoo cars are set up (for now).....but I did not use the primary sensor. I'm guessing thats why the car runs like shit. I'll make another bung and install that as well.

Hoping to get everything sorted out and start tuning off your current map by mid next week:)

You are taking the MAF off when you go to the Adaptronic, right? The MAF is on just so you can drive it on the stock ECU?

I don't know for sure, but I think the primary is the most critical of the O2 sensors, as it adjusts the fuel. The rear one only compares the front to the rear to see if the cat is functioning properly. Someone else that knows for sure can confirm. So yeah, it's going to run like shit as it can't see any fuel in the exhaust so it is dumping in more.

yes I am definitely taking the maf off as soon as the adaptronic is hooked up. and you bring up an excellent point about the o2 sensors. this is probably the biggest reason its running so bad at idle..

A few more threads like this and the decision on which ECU to buy will be really easy. I'm stoked on the price and the list of features is damned extensive.

Has anybody broken it down and done a side-by-side against MS and Hydra. For the money, where does it stack up? I'm not concerned that it can do sequential injection on an 8cyl engine... but what it directly means to the 99+ Miata owner looking at 300whp.

I am looking to do a writeup once I'm done tuning mine. I'm sure Stein can write one as well.

FWIW, I drove my NB for 2 weeks on the stock ECU with both NB O2 sensors unhooked. CEL heaven but it ran, albeit not great, but not terrible either. Idle was fine.

This ECU appears to be great. We'll see how they hold up and how they really perform soon.

You can MS your '99 with MS1 and a CAS for $500 or less. FWIW I could walk you through my exact setup. All the necessary info is in the DIY FAQ. I want adaptronic, but I need a little strange once in a while. (When it comes to the car.)

Sam, Travis did a pretty thorough writeup on his long Adaptronic thread. I just scanned it, but I must have missed it. IIRC, there wasn't anything that the Hydra could do, but the datalogging was slower.

To me the slower datalogging won't be that big of a deal. Since it does it has effective autotuning the datalog isn't as important because I won't be running the datalog through a Megalogviewer application to tune my fuel maps for me.

I just checked an old log that I had run. It logged every .11 seconds. I don't know if that is slow or not.

One thing that I did find interesting about the software. The entire ECU file, with all settings is only 8K. One tiny file.

What extension does the ECU use for datalogs? .xls .txt just guessing

.ecu

For comparison my .msq file is 46k. But that's MS2E, which has all the bells and whistles as far as MS goes.

I'd be curious to know if you have a EGR pending code. Have access to a scanner?

Sorry if I am retarded and missed it, but what is the going rate of one of these systems?

EDIT:

And this is a piggyback with the stock ECU, right?

I'm not sure about how well that adaptive spark control might work. Never seen or heard of that control methodology in OEM circles. Let us know how it works out.

we got ours for 950

Yes I do. I'll scan it today.

here's some pics of mine since I'm bored:
