What tuning software is best for a tight budget?

[e3irsty]

Simple question W.A.R. chip or MS? Want to boost my M20 on a tight budget, I will want to tune myself so which one is easier to tune because of lack of knowledge when it comes to tuning.

I use a Moates emulator & Tunerpro with a Innovate Motorsports wideband

So this Ostrich replaces the ECU? I can plug and play with an M50? Do I have to swap coils or anything stupid?

Megasquirt all the way. You can build a megasquirt 1 for under $200 and the tuning is way more accurate

It replaces the ECU chip only - plug n play (No other changes req'd)

But

(Megasquirt is worth looking into for sure)

*IF* you have a complete definition file for the program on your chip, OE DME is FAR more capable than MS1.

Definition files exist for a large number of OBDI GM applications. MS is a waste of time on those applications because the stock ECM is so much more sophisticated.

What can the unlocked motronic do that megasquirt cannot? Or what does it do beter? I have not heard many say afm > speed density

no. absolutely, no. Motronic is ancient. I don't love MS1 (spend the extra $80 for an MS2 CPU, it's worth it) but Motronic can't hold a candle to it.

Interesting. I thought that with a WAR chip and MAF conversion, the Motronic would be comparable to the OBDI GM hardware, which has been hacked well enough that it can run engines with 4 digit power and single digit timeslips.

big hp and going fast says nothing about an ECU IMO.

no, even the best MAF systems for Motronic are still pretty buggy, because MAF based algorithms and what Motronic uses (closer to speed-density) are very different.

aside from that, the resolution is poor and Motronic is pretty damn slow. no real time tuning, no datalogging, narrowband sensors, switch based TPS, no acceleration enrichment, etc.

Very wise statement.

If you drive it to the strip and back, it can... ;-)

With a 3 bar MAP sensor and hacked code, a $30 7730 can run Hi-Z injectors on a big power small block Chevy, or a $50 7749 can run Lo-Z injectors on same.

Of course they also need ~$300 emulator and tuning software, but result in very good drivability as well as high power. The biggest shortcoming is that the GM OBDI VE tables stop in the realm of 5000 RPM, except for the Quad 4 code masks... but those were never boosted.

I didn't know Motronic was that primitive.

DIY SLC from 14point7.com is the AFR meter that I went with, it was the cheapest wideband I could find.

I got 315cc/min injectors from one of my old cars, a turbo volvo, and threw them in the fuel rail. paired with megasquirt, it's overall been pretty damn cheap for a standalone.
