XFI/Caspers adpt. module

[Fuelie600]

How/where are you guys mounting these. Basicllly, it's the adaptor module I'm trying to find a place for. The XFI sit/s nicely where the original ECU sat, but that dam adapt #%@-----. Doesn't seem to be a clean way to mount this, or even tuck it out of the way. Any tips or PICS would be helpful. Thank you, Brian

[SGRIM]

Mine is mounted under the dash, I have A/C delete so it just mounts on the back side of that plate, plenty of room for the harness.

[Fuelie600]

Should have mentioned that this is on a fully equipped GN ( A/C and heater intact ). Brian

I'll take a pic of mine on the mounting. I basically made a stand off for the XFI and velco-ed the adapter harness to the XFI. Now the XFI reads right not upside down.

Thanks Billy. Should be done fabbing my exhaust tommorow, so I can now concentrate on the XFI install. Brian

[Fuelie600]

Billy, did you get a chance to take pics? Anyone else? Thanks

[gnxtc2]

Sorry for the delay. I was at the track rental @ Atco.

I got the spacers from the those pull out drawers from Sears Hardware. The spacing is depended on you. I believe the spacer are 10-24x 1". I joined 2 spacers by cutting a 10-24 screwhead off and using the threaded part as the coupling. I basically pulled the ECM plastic base and set everything on the bench. After it's set up, just plug away. I also braced the back side with aluminum stock. Did this so the screws don't pull through the plastic.

Hope this helps

Thanks Billy. This is exactly what I was looking for. Brian

I'd lengthen the harness and put it under the seat. I don't understand why Casper's didnt make the harness long enough to actually do something with it.

[Fuelie600]

Right on Jay. The wires are sooo short, it must of been a pain just wiring the adaptor. Atleast 1'+ would allow the module to be tucked up under the dash. Still, it's alot easier than splicing all those wires! Brian

[JohnSpina]

Caspers is listening...

I've had a few customers ask for the adapter wiring to be 18 in. long.

Maybe a running change.

Why couldn't you put the unit under the glovebox? The factory wiring should reach that area, then you could mount it directlyl below it. However, the LED's on the unit wouldn't be easily seen.

Maybe I answered my own question.

JOhn the way it is layed out the factory wiring wont reach over to the adpator above the glove box and then allow you to put the XFI box in the stock location,I prefer to keep the xfi located in the stock ECU location so i can keep an eye on the led lights on the xfi for diagnostic purposes.If the adaptor harnesses were longer this would be workable.
Thanks again for making great product,Keep up the good work
ps, do you have a jumper for a gen 7 (I think the same as old fast)to stock 90 firebird harness?
Thanks Otto

[JayC]

Not to mention as thick as the XFI is, if you have the factory heater box in there, it would be tough to get it under there and it look right.

For cars with the factory AC, under the seat really would be the best option.

[JohnSpina]

I wouldn't extend the wiring more than maybe 2 ft. from the connections. There are some critical signal wires, and the injector drives really can't tolerate that much copper the way it's set up.

If 2 ft. extensions are useable, I'll make them available.

Haven't done any adapters for the GEN VII yet, but I'm getting requests. Also, the BS3 is on the drawing board. Otto, where are you going to mount the EGT logger? The adapter is 12 in. long which plugs into the XFI 10 cavity connector.

John

[Fuelie600]

John, I just purchased the adapter, and as of yet, haven't installed it. Would it be possible for you to extend these wires? If you can, what would be the turn around time and cost? Maybe we can do an exchange? Thanks, Brian

John
Not positive yet John,I plan on laying it out asap.Will let you know.

[JohnSpina]

A bit off topic but, for the EGT logger, go to

www.installationinstructions.com/103300.pdf

for the install info.

Heads up on how it works.

THanks John
What is the range in "F", i dont feel like doing the math

Somewhere around 1900 deg. F. At that termperature, your K thermocouples are glowing red. The RS232 interface can provide both deg. c and deg. f on your PC.

Thanks John ,Just ordered another one,Im going to see some big time import guys this weekend that are very interested also.

[Otto J]

Got it today John,Hey do you,or can you make an adpator to the AEM harness?

[JohnSpina]

Got it today John,Hey do you,or can you make an adpator to the AEM harness?

I've done a couple of harnesses for the AEM system in the past. I believe they use the same connector as the XFI.
If so, I shouldn't have a problem with that. I assume you're talking about the turbo Buick to AEM?

Either way, I have the connectors...

John

[Otto J]

No i have some guys with imports that run AEM and i want to install one of these egt loggers in their cars,They said they have 5 volt inputs,just wondering if they have an accesory plug for the external sensors and if so make a jumper to plug in right in

[JohnSpina]

Actually that'd be easy. I'd just make a jumper with the AEM terminals and instructions on how to insert the terminals into the connectors. They'd probably need four or six inputs, and the module would do the rest. The AEM box uses the same connectors as XFI, so it'd be a piece of cake.

I'll look into the pinouts with their box.

Let me know what you need.

John

[HighPSI]

Otto, call me if you need the sensor gain or offset values for the XFI

[Otto J]

Cal, ill get back to you tomorrow,WE need a setup to install in Pauls car at BG.He has 1/8 pipe fittings in his headers already
I need the fittings also,id rather weld them in than clamp them,John do you have the peices to convert my sensors?
John i will be showing the setup to these guys on sat.I use their dyno and have a car to tune,I think i just sold this guy an 8 cylinder setup

[turbov6man]

I had John at Caspers make me a 3 ft extension from the adapter to the Fast unit. I was able to mount the Fast under the passenger seat, and run the wiring under the carpet. The 3 ft length worked great. He was willing to swap out the shorter extension for the new one, at a very reasonable price.
