Supercharger and Chip Tuning.

[SkorcherX]

I have read over at BimmerBoost that chip tuning for a supercharger is very possible (in fact every $5K kit comes with injectors and a chip).

Where can I find an affordable chip to fuel a DIY Eaton charger kit?

I called up Mark D and spoke with him about getting it done. That was a disheartening conversation. Mark D has a M20 Turbo 7psi chip and I really just want that but for an M50. He explained to me that he has discontinued that chip because everyone that ran it had huge disparities in results. He said that in order for me to get a chip from him I needed to send him data logging and he wanted $650.
I understand the need for logging in order to provide a viable solution, however at $650 I am way over the cost of MegaSquirt 3. I am not opposed to converting to MegaSquirt however if all these company's can sell Supercharger kits with chips, why cant I buy just the chip?

If anyone has any tips for me as to how I can go about chip tuning a M50NV to fuel 7-9psi with an Eaton please let me know.

The other reason why the conversation was really disheartening was when I mentioned MegaSquirt to Mark, he almost became infuriated. I can only assume because this is a direct competitor to his products. He went on to talk about how MS is a joke and the processor in the 402/403/413 DME's is vastly superior, and that the code behind MegaSquirt is terrible and not automotive grade. Now obviously I have not been coding for embedded hardware for 30 years like Mark has, but I think the results people are getting out of MegaSquirt speak for themselves.

Thanks!!!

Emailed Todd over at http://www.turbochargingdynamics.com about obtaining a chip for my DME for a low boost supercharger application. I was referred over to Karl at ActiveAutowerkes. I have emailed Karl and am waiting to hear back.

Good luck :)

Karl can do it.. but he hasn't told me the cost of doing so... He needs data logging from the DME in order to create a tune for me. I have a guy at work that may have the equipment I need to do that... but the more I think about it the more MegaSquirt is sounding to be a better choice. It sounds like its going to cost be about the same either way (chip tuning vs. stand alone).

I don't understand how tuners can sell off the shelf turbo chips but wont sell off the shelf supercharger chips. Makes no god damned sense.

I will be using the Miller WARCHIP and MAF to tune my setup soon. Tuning a centrifugal SC and a Roots type is very different. The roots type is much easier to tune as it really acts like a bigger motor. I can share my timing and fuel map that i will be using with my 30# injectors running 6-7PSI it wont be hard.

I just got done my first test

Drive down to So Cal and have RMS dyno tune it.

just look at hoveringuy's dyno charts.

the CPU in the 402/403/413 is definitely not on the level of the MS3 CPU... it's like 25 years newer technology. MS1, sure, but who wants that?

Be aware thats an "early" Eaton, if i saw it right and the sqrews arent coated and black, and the rpm-limit on it is 14000.

[SkorcherX]

I think I am going to go with an Ostrich 2.0 and TunerPro RT to attempt to tune this thing (assuming I can find a place to mount this thing).

Would love to hear about peoples tuning experiences with it, and snag a copy of any XDF's people might have made for the 402 DME.

Wrong, Its a 5th Gen Eaton M62 from a 2007 Cobalt SS. I know of some that run these at 18000 no problems at all (of course not very efficient but very reliable)

If you want I can share my tune with you once I get there. It wont be hard... its like tuning a 3.5-3.8L instead of 2.5L in N/A state. I will be using the WARCHIP/MAF and 30# injectors should be plenty for 6-7 PSI from the blower, when I do the other side (Turbo for a twincharge setup) I will sell the 30# and go for 50-60# injectors. Send me your e-mail (I will send invite) if you want to follow my blog SC build...I dont post my builds on forums anymore

Ok, just thought you should know if so.
Should have a kickass intercooler if they grear them up that mutch, damn they generates heat.. The lates with black coting isnt supposed to go past 16000.
Had an M65 in my last car and almost melted the pain off the hood.

Just so you know I do have the black coating, it is a Gen5 charger and if you run proper boost it doesnt heat that much but still.. goes without saying any F/I source should be intercooled.

also M65 does not exist.

Eaton is sized by M45, M62, M90, M112 related to the cubic inch of air it produces.

[SkorcherX]

Charger came... its big... not sure if I can make it fit. Will get to play with it tomorrow afternoon.





Intercooler... might be too big as well.



This is the pic that started this discussion. M62 bolted to a M50... looks to be in an E36... The charger was cheap enough for me to give it a shot.
