How to increase throttle response?

[Moto-Mucci]

my apologies if you've already touched on these but don't overlook taking weight out of the car (sound deadening, etc). Also, what rear end is in the car? 4.10s are pretty easy to get.

This is a daily driver and in pretty good shape. I'd like to keep everything pretty intact.

I've got the stock 3.73 diff in there as far as I know. Haven't checked if the PO swapped it, but he was pretty thorough on the mods so I doubt it.

i wonder if you could use their maf and the new "war" chip together...it says that the war chip is for 95 and older cars, so that means e30s, right?

Why is that so hard to believe? Most aftermarket software manufacturers claim around the same gains - with the AFM intact.

From Pelican:

"I recently go a hold of a Dinan performance chip for my E30. The benefits of this chip include raising the factory rev-limiter to 6900 RPM and increases horsepower from 168 to 183. It does this by essentially re-configuring the fuel injection map to advance the timing, fuel pressure, etc. This translates into a dramatic seat of the pants change in power, or as we refer to it, the butt dyno."

because they ALL exaggerate gains. Especially that Dinan chip.

also, a chip cannot adjust fuel pressure, so why would you believe their stated HP claims? ;)

HP claims are what they are (always has been).

I just want to play with it.

I've had a few things rolling around in my head for a while now that this may be part of the solution to.

I talked to them a while back to discuss the possibility of working on a joint project and they blew me off so I just bought one and I'll work it out myself.

Yes, Motronic 1.1/1.3 cars.

Guess you didn't read Taylor's thread either. The MarkD chip is widely considered the best M20 chip on the market, I believe it made around 1.5HP more peak HP than a stock chip.

And it's supposed to be better than the TMS chip that claims a +15HP gain. Think about that.

I know in the Jap market stuff, they would sell a header claiming 10+ HP on your engine. But what they wouldn't tell you is that its some monster cammed, high comp N/A beast where the only restriction left is the header. So on THAT motor it would unleash that kind of power, but not on a car with a "stock" engine, ie no cams/pistons/bore:stroke, etc.

The Japanese have a very funny way of testing and calculating horse power as well.

[nando]

also, often those are peak HP gains, but not neccesarily the gain at the HP peak. so it could be +10hp somewhere in the RPM range, but only 2hp at the peak. Then you get into whp vs bhp and the correction factors for different drivetrains which adds a whole new layer of confusion that marketers can use to sell you their product.

Even the OEMs like to shuffle these numbers around.

The Japanese were famous for it. In the circles I was running in back in the 80's it was a running joke.

+1. this is the biggest cheating method. marketing just chooses the one rpm where their product produces the best gain.

this is some people get 100hp out of a few mods: yeah my p-flow adds 32hp, my exhaust adds 23, my headers add 15, my lw pulley 10, etc etc

Is that a type-o? 1.5hp peak gain from stock?

Please explain.

I understand comparing the peak power points from both graphs - but if one has more power for longer leading up to the peak number, does that not = faster car?

[z31maniac]

Go look for his thread, e30_fiend.

The point is that all these gains are greatly exaggerated.

[nando]

or at least, misunderstood. The mark D chip may infact give you a 15hp gain, but it's not neccesarily at the peak, and the actual WHP increase will be less.
