Haltech Stand alone ECU supercharger 3.4, SILVER BULLET TUNE www.snpspeed.com

Huh that doesn't seem large enough to almost completely bypass the turbo. What's what I was going to run size wise

 

If it were a more restrictive turbo I could see it having trouble. But in the range I run in with active wastegate management it should be able to keep it down, I'll have additional ignition retard in the map if it creeps but I don't think it'll be necessary

 

Anyone have any pictures of the haltech installed? Curious on how it all fits in there behind the glovebox and AC ducting.
Does the haltech fit in the same spot as the OEM ECU and then you just cram the adapter and wiring into any other open space?

 

Do you have an auto or a manual

 

Manual

 

I put it in the same place the OEM ECU was at.
I removed the stock ECU,
Originally I zip tied it to the metal bar above the ecu spot,
If you have the 750 (smaller in size) it will fit down by the fan by that kick panel too

 

Has anyone seen somewhere where you can buy the female ECU connector array, so I can make my own PnP harness?

I've found the male connectors, but not the female, without desoldering a used ECU or something.

 

I bought one from Tuning Technology to make my pnp harness but they are now out of stock. Here is another that comes with a board attached and includes a 3d printed housing https://speedyefi.com/product/denso-76-breakout-board/

 

Ah, I remember seeing that one now, thanks! Guess the problem was I didn't know what it was called

 

Mega squirt might have one.

 

Wait a min. Isn't that for the 3RZ only? Pretty sure the 5VZ has 3 or 4 rows of pins..also may be that I have an automatic..



Think I found the 76-pin manufacturer P/N though: https://www.te.com/usa-en/product-178780-3.html

Not sure of the ecu differences. Mine is a 1997 5vz manual trans that has a 76 pin ecu. You are probably correct though, the auto trans ecu would have to have more pins. Here is the 100 pin header

DIYtuning has been dropping carrying headers left and right. Maybe Boomslang could be a resource?

 

Check with these guys.

I did find that one as well in my quest last night...unfortunately that's not correct either. I think that one is for a later Toyota truck actually, since they have curvature and blocks in the wrong places. Edit: I'm going to double check this. I thought I had seen something last night to disqualify it, but now it looks right.

Here are all the 98-00 headers from my FSM:


Looks the same as the 01-04 (w/o electronic control) below.

Here are what I have for 03 Taco (presumably 01-04, also 4Rs):
ETCS is electronic throttle control.

 

Wouldn'tcha know it? The 98-00 non-Cali 5VZ Auto is missing too.

 

This may help you guys https://people.well.com/user/mosk/images/Early_Tacoma_ECUs_v2.pdf

 

Always good to get everything in one place

 

Call them.
