would've been sweet to have a real PnP, with base map and all.
A couple guys offered such a true PnP version for our much rarer starions, with amazing results for the dollar value.
Surprised nobody stepped up, for the far more popular rolla

Edit: They have a "base" map sorta already for me, just have to edit some ignition stuff and its set already. Its based off an MR2 4agte car.

As we do more of these Application Docs we'll put them online here: http://diyautotune.com/diypnp/models.html

i suck, you rule...i get it

Tested it on a 1995 Miata as well. Converted that one to sequential Coil-Per-Plug ignition using this box. Works like a charm.

Tested on a 1984 RX7 GSL-SE (had to wire it in here, but wanted to test it on this ignition system). Works great.

Tested on a 1995 Honda Civic EX. Again... Flawless.

We just released to the public on Friday so if you want to take a wait and see approach you'll have to give it a bit of time. But FYI we just announced this promotion last night to help get the word out: http://diyautotune.com/diypnp/diypnp_promo.html

Looks to me like the AE101 SilverTop uses what we're calling the N76 connector:

Here are two pinouts (manual and auto):

And here's the connector in our kit:

Perfect match.

And the Blacktop appears to be a perfect match too-- http://www.club4ag.com/faq_and...k.htm

20v'ers. Eat your heart out .

Most issues I've ever had have been problems I've caused myself.

I've corrupted my firmware when I tried to connect to the ECU with the wrong software configuration (setup for older firmware). That's an easy fix, reflash the firmware and reload your map. It was my mistake that caused it though, and the new tuning software (TunerStudio) makes it harder to make this mistake.

I've mis-wired things and had to track down my mistake.

Other things of that nature. That's not to say that anything is 100% bug free (no system is, and the MS is among the better probably). But typically if I do run into a bug it's when I'm using a pre-release (beta/alpha) release of the software/firmware rather than the release code which is pretty thoroughly tested.

Hmmm.... trying to think of any other examples. If you have low battery voltage you can have a hard time saving the maps, but that would typically be less than 9v.

Really man, these things just do their job and do it well. I was out on the salt flats last week crewing for Gary Hart again, he ran 248mph this year on an MS1. We wouldn't trust a world record and a motor worth 10's of k's to anything we didn't know we could trust.

Too bad that motor had oiling issues on the backup run this year, the passenger turbo didn't get enough oil and ate itself. Motor kept going though, just with questionable oil pressure and might have hurt the bearings. Needs to be gone through now. We almost got Gary his red hat this year. We needed a 245mph average between the two runs to do it. If it had just held oil pressure for 15 more seconds..... oh well.

Keep a close eye on the oil pressure gauge (right Mickey-ear). At about 1min it starts to drop, keeps working down, and by 1:30ish there's no pressure. Then you hear the turbo say 'bye bye' and the car fills with smoke for a few seconds.

Can this be done with this MS setup on the 20v without having the dizzy in the back?

Mike

That's also an identical ignition trigger setup to the RX7 we tested, which is why we made sure to test that vehicle thoroughly. That's another car that in the past we had to jump through hoops to properly condition the VR signals on, and the triggers were cleaner now with this new box than they have ever been. It runs great.

So you should have no problem using a DLI system- CAS with the coils packs. The 16v DLI (like on the late GZEs) and 20v DLI are pretty much the same internally, so neither should be a problem. If somebody has one locally they can drop off for a few days (Atlanta area), with a virgin harness, we've got a deal for you. You buy the kit, we'll build it, install it, and get it running for free. And if you want it tuned we'll do that for cheap. We're offering this once for each type of vehicle.

Both of these options are covered for the 4AG Corolla (FX16, AE86, AE92) here: http://diyautotune.com/diypnp/....html

Im doing the GM sensor AFM bypass as well as a wideband on a stock bluetop for now. Well, it has bolt ons so we'll see.

im impressed with the fact you'd trust it on an expensive motor and this makes me more confident in using it when/if i decide to build my GTS' motor.

how does the driveability on the stock bluetop compare to the stock ecu??

Driveablity is really as good as the tune. Properly tuned it is superb. Poorly tuned you'll hate it and wish you had a stock ECU (which was properly tuned and was therefor superb, for the stock motor).

On a stock or mild motor I'd expect a 5-10% hp/tq improvement once tuned.

does the MS pnP use the stock o2 sensor or is it purely speed density?

btw, did you guys upgrade the fuel system at all on that mr2??

would a walbro 255 + a set of 550cc injectors allow me to hit 400whp on a bluetop (with low comp pistons) ?

You've got the capability to make the vehicle cold start and warm up beautifully, and still fire up easy on a hot day after running it hard and shutting it down hot day too. The tuning software gives you full control of all of this, and you don't have to compromise. If you need to fine tune cold start, you fine tune the starting temps for cold start. Same goes for warm, hot starts. But again, in my experience with the MS2/E code this is far easier to do than it used to be. The defaults work fairly well with only minor adjustments on many vehicles.

We can use a narrowband or wideband o2 sensor for closed loop feedback and EGO Correction, or we can ignore it. You can give it as much authority as you want, and you can have it make adjustments as quickly or slowly as you want. Full control.

The MR2 uses 440cc 7M injectors and a Walbro 190 pump. That pump sucks to change BTW.

Lastly -- your injector sizing question. For 460 crank hp, at .6 BSFC (I'm assuming you're turbo), and max duty cycle of 85%, at standard 43.5 fuel pressure, no that won't do the trick. You'd need about 850-860 cc injectors. Start increasing the fuel pressure, run a very efficient setup with a lower BSFC, or run the duty cycle a bit higher and you'll get a bit more out of them. These are the general guidelines doing the math... sometimes you can push them a bit further though than the engineers like to think. Push too far and you'll run out of fuel at WOT and 7000rpm and that's not a good thing.
