Hello all

[dr4ck0]

Greatings,
I'm portuguese and i'm living in venezuela.
I'll start to customize my '72 camaro
I've chevy 350 motor

[AndreyB]

Hey dr4ck0!

Something tells me a 72 camaro is not fuel-injected, is it? Are you planning some kind of a conversion?

[dr4ck0]

thats right,
my chevy 350 motor is carburated. I'm planing to do a conversion to efi.
i pretend to use oem parts as tps , map ,maf and inyectores.
I'm designing the butterfly admission

[dr4ck0]

i'm also want to get involved in this proyect
i've good knowleg in mechanics, but in really i'm an electronics engineer with experience in asm programing

I like your skill set and we can definitely use some help!

Do you have stm32f4discovery available where you live? What are you planning in terms on the ECU hardware? There is a kit for the simpler board and the fancier board still have some minor but nasty tracing issues.

[dr4ck0]

i'm waiting for the discovery board from amazon and i'll buy the frankestein board and the 6 inyector driver also.

[AndreyB]

Frankenstein has 12 channels, do you need more than that? Why the 6 extras chennels?

[puff]

yay! i bet its almost the same as my rover v8!

[dr4ck0]

the expansion board of 6 injector y 4 more advanced features like ingnicion control or something

[dr4ck0]

whe never know what the future reserves

[kb1gtt]

I don't think I quite follow, Frankenstein can direct drive 8 injectors, so one for each cyl. are you planning for staged with two injectors per cyl? Are you planning for high Z or low Z injectors?

[dr4ck0]

i'm planing hi-z injectors in first place
second i'm planing use 2 injector per cilinder i'll explain:
i'll use an water/methanol injeccion sistem to elevate the octane level at boost for that i'll use 2 injectores
i'll use 2 fuel injector per cilinder---one for normal boost level and the second one as aux in high boost level
take in mind that here an full tank of gas is cheaper than an cockie (0.32USD per tank)

[puff]

wanna live in venezuela

[dr4ck0]

lol venezuela is nice
nice chiks
good weather
ok its a 3th world country but who cares

About ASM programming, might you have interest in the ETPU for this SPC56x series of chip? It doesn't have an easy to obtain compiler, so it's programmed via ASM. http://www.st.com/web/en/catalog/tools/PF259195 Using it is on the long term goals, for a variety of reasons. The compiler has been a significant problem.

What happened to Freescale MPC56xx is an expensive slow part? You posted that to ad nauseam along with TPU stinks. Just curious? 450 MIPS seems decent? Even MPC5634m has a combined 160 MIPS…

Also that MPU can be hard to get, changing to 4MB version and availability is acceptable.

[kb1gtt]

I would still consider both the SPC56x and the (Freescale exact match) MPC56xx chips to be reasonable expensive and reasonably slow. You can get much better $/MIPS ratio with other chips and you can get other chips that can pump many more bits much faster. However that SPC56x is supported by Chibios and is automotive grade, so there are some benefits. It's fast enough for most applications, including a staged injection V8. For a hobby, I don't see a huge need for automotive grade, and I feel that industrial grade is good enough quality, but automotive grade does have some enhancements in terms of safety. The fellow mentioned he may be interested, so I inquired.

Status update: the manufacturing shop has just shipped the 6 channel boards to me, I should have everything you've ordered around Wednesday.
