may be some one can please reccomend a cheap " sequential " ecm system set up then for a gm plug in application to suit my 1991 m.a.p speed density 8 t/b set up ?
any ideas of brands please ?
thanks
shae

You would be better off trying some of the local EFI tuning experts for recommendations as you are going to need some dyno time to set up up correctly.
Who did Boschvette get to set his up?

emo-vet

hi rod,
thanks for your reply back!
just wanted at least a reccomendation on a sequetial type ecm thats all.
im not sure who tuned boschvettes 8 t/b vette!
but he did say he would send me his tuning tables/info though.
its a shame no one around here cares to reply on this forum besides you!
must be a bit out of there league i guess!!!
cheers

Holley Commader 950 uses MAP, and it only costs @ $600 total if you re-pin your harness yourself.

Or www.jimsperformance.com will repin the harness for $250

The mob that sells the intake should be able to steer you in the right direction re ECM unless you and Boschy are the only ones in Oz with that intake.
Is that a similar setup to what the V8 supercars run?
Maybe someone who knows their way around Super cars can set you right.

I´m running this in my -90 C4: http://www.autronic.com/page_files/smc_kit.htm and a cheap Innovate LC-1 wideband.
Not a plug-and-play system but it´s sequential and it´s been performing very good the 3 years I´ve used it. It´s an Aussi company so it might be fairly cheap in N.Z.

hi rod,larry,bogur,
thanks for the replies and help !
due to the cost and stuffing around of rewiring and repining i have decided to buy the haltech e6gmx system plug in and play set up.
this 8 t/b intake Rod is the same sort of intake that the proffesional v8 super car race cars run on the track.
cheers

hi jussi,
thanks for your reply.
so how do you find the haltech e6gmx please?
any good?
how about tuning capabilties,any good?
what about viewing raw engine data?
what about performance wise any good ?
easy to install?
i heard that there is two wires to modify to install?
where did you fit your e6gmx please?
any pictures of final install ?
sorry for all the questions mate!
thanks
shae

I would check with Haltech,

Their site states
"The Haltech E6GMX is a user-programmable, fuel and ignition engine management system designed to plug-in replace the older AC Delco OEM system"

From the online info it looks like it has two plugs (24 and 32 pin ) the same as the "165" MAF ECM used in the 85 - 89 Vettes and Camaros
( same as VN/ VP Commo).

Your car has 4 plugs on the "727" MAP ECM ; completely different style so won't be plug and play.

I bought a Haltech E6GM several years ago and never installed it. It's for sale. Any one interested in buying it, PM me.

rodj

How much?

emo-vet

hi rod,
well thanks for the info mate!
so what do i do now?
i have already brought this e6gmx!!
will be delivered on monday coming.
surely i can modify it couldnt i ??
i was told there is only two wires to modify then i can install it!!
i thought my ecm 1991 vette is the " 730" ecm,not the " 727" which is the older style isnt it ??
thanks

Poor choice of words I think. Like rodj stated, it's not very popular in the states. I'm using the DFI 7 piggy back to the stock computer so I retain gauge functions.

rodj

165 is 85 - 89 MAF computer (two plugs, as shown on Haltech site)
730 / 727 are '90+ Speed density (MAP ) computers.
Same computer, just Vette 730 is in weatherproof housing for mounting under hood and it has 4 plugs ,not 3 like the 727.
The Haltech is MAP but appears to have 2 plugs like 165.

"surely i can modify it couldnt i ??"

have a look at the wiring details for '85-'89 and '90

The basic inputs to run the engine are very similar .I don't know what else in the car the ECM controls as the Haltech problably won't have provision for those.

I probably have the correct 165 plugs to fit the Haltech if you want to start cutting wires.

emo-vet

hi rodj,
thanks for the info mate!
you have been very helpful.
how much do you want for the 165 plugs please if i need them ?
thanks

The unit I have is an E6GM, NOT an E6GMX. I'll take the first/best offer over $350 (US).
