M60b40 performance chip for e30 v8 swap

[RosiE30]

I've been looking through the threads and didn't find exactly what I was looking for, if it already exists feel free to direct me to it.

I'm getting ready to start my m60 swap into my e30 and I remember reading about a decent performance chip for the m60 I just can't remember where I read about it, if anyone has any info on one please let me know.

and also any other minor performance upgrades and advice before I put engine in would be greatly appreciated too.

Thanks, Justin

Dinan has one for about $200, I bought one a year or so ago and haven't installed it yet.

Really? Interesting, I'll check it out, if you get around to it before me let me know how it goes, thanks.

There's a bunch out there; Dinan, Jim Conforti (via Bimmerworld and Turner Motorsports), Mark D'Sylva (EAT Chips), etc...

DUDMD on bimmerforums also sells one pretty cheap, that everyone seems to love. I bought one when I did my swap, and spent over a year and probably close to $2k replacing every part of my fuel injection/ignition system trying to figure out why it ran like shit, constantly stalling and running pig rich, before I found out it was his chip causing it. So, use with caution. All of the e34/e32 guys seem to love them though... And he's posted a few dyno plots showing nearly 280whp out of an otherwise stock m60.

I'm currently using a Mark D chip. Other then the removed top speed limited and increased rev limiter, I don't really notice a difference in power over the stock chip.

did you notice an increase in throttle response or anything like that or just a raised r3vlimiter Justin?

Nothing noticeable, in my opinion.

Honestly, my throttle response is shit, mainly after decel fuel cut has kicked in. If I leave off the gas and leave it in gear, coasting and engine braking, it takes about 3 seconds until it goes into fuel cut. Then while it's in fuel cut, if I get on the throttle, it hesitates for a second, makes a weird sound, then finally gets it's shit together and starts hauling ass. It's only a 1/2 second or so delay, but it annoys me. I thought it was that stupid wedge plate on the throttle body, so I swapped in an m62 throttle body, but it made no change. Every single part of my fuel injection/ignition has been tested/verified/replaced and is working, so I just gave up and now assume it's normal. It did it on my m60, and it does it on my new m60b44 hybrid engine.
