Same as most other ECU's.

Some older ECU's and ECU's for B200 engines have a lower level of fuel cut though (software limited), but that is fixed with the chips.
so what? a 960 AMM and keep the pressure within ~15PSI and i should be ok?

Bigger AMM = less air reported to the ECU = less voltage.

By using an AMM suited for your application, you can run any amount of boost you like.

You should be able to use any of the LH2.4 EZK once you put the new chip in.
You ECU might me the same as mine (560). you have to check.

I have updated the last part of the first post to include some questions about EGR.

Tell me if you have any other relevant questions that might be intereting to incorporate in the same post.

You need to be more specific.

Year and engine type please.

A bit off topic, but if someone wonders here are the pictures of B204FT TCU unit: http://linuxfan.org/~ipdown/mybrick/tcu/

It may be LH2.0 (or even earlier version) if you have a B230FT. I do not have chips for those.

If you can check the ECU number it would be great. Then we would know for sure.

I'm to understand that the black EZK boxes are not directly chipable & require a daughterboard? Or is this an instance that I need to pull it & check?

Yes, you need to pull it open and check, good possibility for chipable black boz is -119, found in early n/a 16V

Now that is odd, a 86 760 should be LH 2.2 with a b230ft

Yeah. Then it would have LH2.2, but the B23 would have an older EMS.

As far as I know, all B2x engines came with older stuff than LH2.2. This goes for Europe though (where most of them had ML1.1).

B1x engines on the other hand, can have LH2.2, but those are not sold in the US (360 sport and 460/480, ES and turbo).

Turns out that it is!

Yup, you're right. My bad. Things I learned in the 80's are slowly eroding away.

The whole board looks like the old SIP chip carrier though. Like those lasted a long time...

not

Megasquirt and chips are two different things. Chips upgrade the stock ECU/ezk, and Megasquirt replaces the stock system entirely.

The chips for LH2.2 and LH2.4 from me still have the stock rev limit at the moment. On my chips for several of the Motronic cars (M4.3/M4.4/ME7) the limiter is sometimes changed depending on the engine used.

The chips will eliminate the EGR function, yes.

I don't exactly understand where you are getting at, but yes.

[QUOTE=yamahapro;2423970]and just a few more questions. do green top injectors flow enough for higher boost?
For around 15psi on the 13c turbo and T cam, yes.

If you add bigger injectors at the same time it will.
