Looking for advice

Unread postby g3mustang » Fri Mar 18, 2016 6:55 pm

I'm looking to do a svo/turbo coupe swap. What are some of my best options in regards to tuning support, strategies things like that?

oh i see now, i thought you meant you had one already

nah best bet would be to use a newer better supported ecu

The 91-93 4cyl C1A1 is completely broken out im BE by derek

otherwise, gufb or cbaza... will do nicely

soon ill be working on a strat for the 2006 eec-v ranger truck ecu, thats only if i cant pull a switch a roo

La2 is broken out as well, if you grab that harness it'll work fine until you swap in your distributor less GUFB setup later ;)

Which would be a better starting point? GUFB or C1A1? I'm currently running an LA2 with MAP sensor and distributor.

I have a 94 4cyl, dual vane crank + edis setup. I also have a turbo+manifold lying around, is it a lot to swap in a GUFB computer ( I ask because I have one already and wouldn't mind having full tuning capability)

Other than the settings in the tune, do you have to re-pin the ecm to line up with edis and only 4 injectors? (my GUFB came from a 93MAF 5.0)

"re-pin" as in move all the pins in the ECU connector to new locations, or is it just add for the injectors.

I looked at the ignition write up, pulled the files, altering the tune doesn't look like an issue at all. I don't mind adding the wires to give it four injector control spots at all. Is there more that I would have to rewire?

the dual vane with module is dis, not edis? that is probably why i was confused on the connection write up. It didn't make sense to enable "high res" when essentially the dual vane is no better than the pickup in a distributor other than being mechanically more "solid"
So in the tune it's set like any other TFI type setup then?

Here is what i'm seeing to run:
HP_hidres = 0 since it's dis not edis
HP_cid =1 since it does have a cam position
HP_CIDSEL = 0 since cam is a hall effect
MHPFD = .99 Is there a reason not to just move the slider all the way to 1.o?

GUFB doesn't have "ign_type" i don't see DPL_DHP in there either, or am i just missing it? will gufb mind running both coil packs, or am I only going to use 1 of the two?
Is this type module the "grey" "push start" type.. or is this setup the computer controlled dwell? Is there a way to easily tell with aftermarket modules?


as far as running GUFB on only 4 cylinders..
NumCYL = 4
InJ output =4
ENGCYL =4
Sarcharg =140
NUMEGO =1
DEGPIP =180
INJOUT =4

FN1329 ....i have 8 data cells, do i zero the extras, or repeat? ie.. 13421342 or 13420000

FN1327 =1
MHPFD =.99


Now looking through the methods, could someone also run "2" HEGOS, and set it to "bank fire" , change the number of injectors per output to "2" set the number of injector outputs to "2" assign the each cylinders in the injector ouput port mapping to their respective banks, and run it like that? would that also be an option, or not a good idea with GUFB? I mean it would look really cool with two little tiny fabbed manifolds two tiny turbos and a dual setup :D :D


If you were going to use EDIS with the 35? tooth crank wheel What computer would be your first choice, and what donor would you look for? a 4.6 computer? I assume individual coil might be a bit of a pita and not really worth any benefits it might have over waste spark coil packs.

sounds like u got it

dis is an external tfi and is ccd

no leave it at .99, 1 is an incorrect value

the ecu doesn't control the coils the tfi module does - dis module

those other scalars dont exist in gufb just ignore

fn1329 the leftovers doesn't matter

yep you can do dual hegos if you want, not ideal on a 4 cyl since idle conditions and low exhaust flow conditions could cause some incorrect hego readings, thats why no manufacturer has ever ran dual hego control on a 4cyl to my knowledge, but go ahead and try it out and report back, keep in mind the hegos go in the downpipe after the turbo, hegos can never be mounted pre turbo

if your going edis the best option is to use the best eec-v, the 03-04 luxury sedan ecu and RZASA on the homepage, youd have to configure it correctly and may have some issues with the firing order on crank but I would give it a try if the opportunity presented itself.

is there any real advantage to SFI on these compared to just setting it to bank fire?

can i set it to "1" bank, and not have to rewire injectors, if i set "inj to output" number to 2 so that it knows there are two injectors per output pulse?

The current computer puts 1&4 on injector output "1" of gufb, and 2&3 on inj #2 of gufb

not really but every little bit helps, no reason not to

i dont see why you couldnt

be aware that the svo uses low impedance injectors, you will have to swap to high impedance to use any other ford ecus

I knew that from long ago, learned it the "hard way" back in 2002 lol

This is in a pickup still has the stock 2.3 ranger injection on it. I didn't swap anything on yet, setting up a computer i can tune, making it run on that is going to be my first step on this build, then I'll start modifying components. I figure once i know my computer options, i'll build within the limits of what i can easily control This is after all, primarily a gas milage little pickup for running errands, i'd just like for it to not struggle to go up a small hill with 90hp lol


I was thinking of just picking up some 48 lbs ebay injectors to keep the cost down, since V8 sets are less than 100$ typically, once i have a comp i can tune, since having a stock motor under it and that being the only mod, should make it relatively easy to dial them in.. Then i'll add the charger and just a bit of boost.

I would never buy or recommend getting injectors off ebay most are junk, best to buy direct from a wholesaler so you know your getting genuine pieces

call chris at power adder solutions and get a set of 4x 80lb injectors, should be less than $200

would be much cheaper than buying a hundred $ set of injectors off ebay, spending countless weeks and months trying to dial it in just to wash down the engine and have to rebuild it then spend an addition $200 to buy good injectors and toss your ebay ones in the trash

significantly cheaper and easier to do it right the first time
