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:
