Lol, not really a problem (peaking behind the door ). She knew about my hobby but the house took a lot of energy and work last years but I have always been doing some Fiero stuff now and then. I just need to start posting again about the little progress I make here and there, after all this has become a 10 year+ project and there is no reason to rush now

When I got my Fiero here after more than 5 years of storage I got it cleaned up and looked over everything I did and what needs to be done. I am happy to find the stuff I cleaned/restored/painted is still in a great shape, still there is a lot of work to do, the first goal now is to make it technically running. Engine, cooling, brakes, battery, cluster...all of it will be custom but I want it running at a certain point. Working on all of that, most is research and fabbing now, again. I do have some progress on the interior too but I have come to the decision this is a car that needs to be able to move and not something to look at and keep dreaming




Things I am working on now:
- wiring, freaking wiring of all this, wiring of the L67 to the ecm, tuning, getting rid of the old ecm wiring, tablet OBD2 dash taking all the data of the ecm OBD bus.
- intake, cooling lines etc. With the engine still testfitted I want to set up everything to fit before final install.
- setting up Intercooler tubing
- setting up custom fusebox, wiring etc etc
- more -

Things I still have to post:
- redesigned front mount battery setup
- brake vacuum via EGR port
- front bumper 'correction' piece
- doorpanels progress
- trunkpanels progress
- more -

I am not done.

I have been busy to trace all the wiring for this engine swap. I am not a wiring guy but all of this needs to work together. To me it is important to know what goes where and what it does and I have a clou if it doesnt work. I have labeled all the ecm side wires, the engine side connectors and wires ( I think I am still missing a cam and crankshaft and one knocksensor connector)

I am looking for a setup with this L67 engine custom wired to its ecm, deleting the Fiero ecm and cables, deleting wiring to the fiero gauges, taking info from the L67 OBD2 port to run gauges on a tablet replacing the cluster, and analog lights for turn,beams etc.

I have been thinking a lot of ways to do this effective/efficient and they have changed over the years, and this is where I am now. Tonight I started to remove the center console, pullled out the original ecm wiring, I welcome any good ideas what to do and why..

I envy your professionalism.

as far as wiring goes, how familiar are you with the L67? This place is obviously an amazing resource.
At one point I think I had wiring diagrams for 98-00 and 02 layouts.

My advice is just to consume as much as you can, and get a good tuner. My understanding of how it works grew leaps and bounds when I actually start taking readings and start tweaking things.

Thanks ! But if I were a pro it wouldn't take 10+ years
The fact I am doing so many things to this car means that 10% of error already makes it a pile of non running junk. I really try to do things right the first or second time. Most of it is second time

Thanks for the advice and you are right. For this swap I have been reading and collecting info for about 15 years, I guess I have all the needed diagrams and more.
I bought a DHP Powrtuner from Charles at DHP about 10 years ago, since I had to wait 2 years for delivery he upgraded it to the unit with 3 analog inputs, may come in handy to log the wideband O2 sensor I plan to get. I noticed the DHP forum and support are gone now but I found a torrent last night that contains the most recent software, additional scanners and bins. I will dive into the whole scanning and tuning proces when I have finished up all the wiring. I know now where all the L67 stuff goes but the next step is to put it together and what to keep of the Fiero wiring.

In the meantime I think it might be a good idea to start looking for a PT basemap that is close enough to my setup. It seems every L67 engine responds a bit different to mods and setup, even more when in a Fiero. So I understand there will be a lot of scanning and tuning required but it would be nice to have a startingpoint...

For a PT basemap these are the specs of my engine / setup and some ?? :

Modded L67 Fiero 5 speed
Cluster gauges via OBD2

282 Getrag manual (all automatic transmission codes deleted)

4" airintake
N* MAF
N* throttlebody (newer style)

Gen 3 Supercharger:
inlet machined to match N* intake 77mm
Outlet machined for ZZP S2 intercooler
MPS pully 3.0 (+ 2.8 and 2.6)

ZZP S2 full stack intercooler

Lower intake:
machined to match IC outlet
ports gasket matched to heads

Heads: stock but gasket matched intake and exhaust
Injectors: 36lbs (stock) may need to step up to 42,5 with these mods ?
(PRJ fuelrails, stock FP regulator, Walbro 255lph fuelpump)
Stock cam
(Arp headbolts and rocker studs)

Front exhaust manifold: ZZP powerlog
Rear exhaust manifold: stock
Exhaust, will be: 3" to cat, muffler 2x 2,25"
delete second O2 sensor
delete EGR
delete Evap
delete boost solenoid
delete more sh!t

Fiero fan control via the L67 ecm

Getrag 5 speed VSS to L67ecm. Need correct speed vss to ecm>OBD2>cluster (NOT the original Fiero cluster! I know about Ryans conversion interface but I will take OBD2 from the ecm)
option 1: custom converter fieropulses (rate/dig) to L67ecm (different rate/ana)
option 2: forget OBD2>cluster part, use GPS of tablet for actual speed

I may edit this if something comes up I didn't think about... which is most likely the case

maybe I should say I envy your perfectionism then lol

I think you can get away with stock injectors up to a 3.0" pulley and no cam/rockers
Knock may be your limiting factor. W/o scanning it's impossible to speculate but I had a very similar setup at one point and stock injectors were just fine.

Swapping injectors is very easy, so IMO spare the expense until you scan it and know for sure.
Of course.. I'm kind of cheap so it's easy for me to say that.

Here's a quote from Ryan at sinister performance about knowing when you need bigger injectors.


quote
To tell that, you need to know Injector Pulse Widths at WOT and A/F ratio. As long as your IPW's aren't exceeding 21ms and your O2 voltage is above 0.915v at WOT (or 12:1~12.5:1 a/f ratio or richer); the injectors you have in your engine now should be meeting your needs.
