20V Quads on modified 16V Bigport / ECUs

[GeeEss]

I called up a local Adaptronics agent to see how much setting up their baseline e420d would cost on the Bigport(+ST Quads); got a quote for $2850+. I.e. $1000 for the ECU + another $2K to set it up. I now understand why people just throw in a BT 1/2 cut. . . .

Has anyone got an alternative which doesn't involve a laughable amount of money?

1. Has anyone bought an eManage / other standalone ECU and wired it up themselves?
2. Are there any cheap-ish piggyback units that will do the job?
3. How much lost performance / economy are we really talking about if I just run with 86kW ECU?
4. Etc Etc

Engine Stats: Comp 10.5:1, 264 Cams. Headers, 2.25" exhaust, hi-flow CAT.

Could have a look into a Megasquirt, depending how brave you are.

does that $2k include the mechanical side of changing the intake over to the 20V ITBs? and wiring up the new ECU? or just $2k worth of tuning time?

[GeeEss]

No; I said I'd do that. The $2K was just the tuning side. He said he'd need the car for a week; including a day for 2 Cold Start tests.

It's academic anyway; I have no intention of paying that kind of money.

I think if you talk to Adaptronic, you will find that the ECU now comes
with a base map pre-installed. That will be good enough to get you up
and running. FWIW, I bought an e420c from Anthony**, and he installed
a base map of his own in the unit for me. I installed the ECU using the
long Adaptronic loom spliced to plugs salvaged from a spare smallport
factory loom.

Since then I have messed around with the tuning myself (there is an
auto-tune function for the fuel map) and while my tune is not perfect,
the car starts and runs fine. Maybe one day when I get the car certed
and road legal, I will take it to a tuner for some dyno tweaking.

So if you have a suitable laptop, and don´t mind investing some time
in reading the manual, you can be up and running for the cost of the
hardware.

i got the same set-up;
get the custom loom from Anthony (loom + coil on plugs around $750) if u can find a CAS for decent price it would be really nice to do coil on plugs.
contact Anthony if you buy the ECU + loom form him he will take care of you, then tell him ur specs he'll load a base map then u can drive it for the Tuning Place (in melb Full tune $600 they keep car for 2 days)
with custom loom you have to connect only 5 wires. so easy , it's really really neat.

I picked up an old second hand adaptronic for $400, got it all wired up for $250, and got it tuned for $600. Been driving it ever since no problems. Not the best setup though.

[GeeEss]

Thanks for that; I'll give him a call. . . Re. CAS+Coil on Plugs however - I'd probably give this a miss.

What's the advantage of this set up anyway and is it really necessary? I mean, even using your figures of $750+$600. . +($1000+ for ECU?) I'm still looking at $2300 minimum; . . . more probably $2500.

PS: $2K tuning quote I mentioned previously included a new MAP Sensor; he said it wasn't advisable retaining the 23 year old OEM unit. I'll ask Anthony about this as well.

[Animal15]

Coil on plugs is not necessary.. but it gives strong spark it's up 2 u man. yeah call Anthony, That price is for including map + Air temp sensors.
But i thnk if u gonna get a Brand New ECU + proper Full Tune gonna hit you at-least 1.7k (if u done the wiring by ur self ).
But remember this in modification side DO IT ONCE DO IT RIGHT. ( cause i learned it harder way, cost me a lot.)

[GeeEss]

I sent up my Harness to Anthony today; asked him to put in extra connectors to enable easy change-over from D.I-to-DLI as I still can't decide if I should run it with Dizzy ignition or Coil on Plug (plus I can't find a GZE Dizzy).

I want to keep the Bigport Dizzy intact (i.e. not cut off Rotors) in case I need it later*

I suppose I can look for a good 100kW Dizzy (not that easy to come by either these days) and fabricate a Cover from the GZE unit / 19121‑16020 (might be NLA tho) by epoxying another section onto OR I could buy internal 4AGE Dizzy Dust Cover (19121‑16160) and silicon that in place.

Thing is, whatever I do I'm looking at a 20+ year old Dizzy; as a minimum, oil seals will have to be changed, and maybe the spiral gear as well. . .

PS: Can someone confirm that Adaptronic ECU won't work with a 4-rotor CAS?
