Not at all.... I hope someone does go faster.

I just know someone is going to have to set up their car better than we did. We made a bit more power them most of the people that are trying to beat us and they are still close. Hell, We trapped 142 and I think the next fastest car is around 135 or so. That just goes to show how much the setup and weight changes things...



Oh, And I was one of those people who had a motor on stand by and did'nt care about the stock one in the car. It was worth it for us.

I have been faster than 135 on the stock engine/ecu, but I aint going after any records. I just like to go fast.

How fast have you gone? What head was on the car? Stock valve train?

6.757/10.362@108.55/136.94 is the best I have gone. Stock head and even stock headstuds. Magnus v5 intake manifold, fp4r cams and fp beehive springs. My own non hta 35r turbo kit. E85 fuel.

Sorry Dave for the sidetracking.

No problem. Thread is off track at this point anyway.

 

not sure if this question has been asked, but how much more power would the car put down if aem ems was used instead of stock ecu?

 

Here we go...

 

dtrackstar,

In the past, as everyone knows, I was very quick to suggest the AEM EMS. I was convinced that big injectors, big cams, MAF pipes etc., were all impossible to get to run correctly. I didn't even bother to try and turned away those types of tunes on the stock ECU.

With Project White the one big thing everyone wanted to see me do was use the stock ECU. I almost didn't do it, the wiring in the car was cut off and I was going to take the easy way out and just put a stand alone in it. With all the "encouragement" from everyone on different forums I decided to find a wiring harness, repair mine and use the stock ECU.

Now that I have done it, found some people in the industry to help me figure out all the new things available for the stock ECU and spent some time on it I really couldn't be happier with the car. It runs nearly flawlessly and each day I mess with it, it's a little closer to flawless.

So, with all that crap said, "How much more would it make on a stand alone?"

The answer is, I don't know. Here is why I can't answer for sure, this is quite long too.

1. The ROM file in my car is highly modified at this point, thanks to a lot of people who put a lot of time into the stock ECU. The knock tables are modified. Previously I was told that was not possible, well it surely is. This lets me run a more aggressive tune than was possible in the past without having the knock sensor kick my butt.

2. If I were to use an EMS on the car I'd use speed density. IF I didn't use speed density and kept the stock MAF then I'd say the power would be the same with the stock computer compared to the EMS.

3. I know for certain the stock MAF is a good 15 whp restriction on a 350 whp car, proven it already. That would be the biggest gain.

4. There is a patch thanks to jcsbanks, that allows the stock computer to run speed density, which means there is no more MAF.

Finally, the answer, if the stock computer was converted to speed density there would be no difference in power between the stock ECU and a stand alone. I have not however converted my car yet.

 

Hell just froze over.

Props on the humility and optimism.

 

Dave, do the SD patch, I would love to see what getting rid of the maf pics up on your dyno. I have no dynos around here, but I did the SD patch to my car and it def picked up some power up top.

I'd love to see how my car does with SD. Another 15whp would be great!

 

I am working on the ECU pretty steady now because I am driving the car constantly. I don't like doing too many things at once. I need to perfect what I have first before moving to something else.

I was having some crazy high idle problems on initial cold start, fixed that yesterday.

I was having a tough cold start on E85. I got the cold start enrichment map xml's today loaded so it should be a quick fix for that.

I wanted to install the alt switching maps, got that done, works perfect, thanks again Jack of Trades.

Today I started installing the AEM wideband with the trick wiring harness fastfreddie hooked me up with.

So I'm close to moving on to the next change, which will SD. First though, I am taking the car back to the track on the stock MAF and seeing what it will run.

Then...................SD

 

fathouse, were your times that you ran on the SD patch or on the stock MAF?

 

Have you considered somehow making the stock ecu work off a MAP sensor? Similar to the SRT-4.

The srt-4 does not have a maf. Basically they run off the narrow band o2 sensor during closed loop (vacuum operation normal driving) and then the ecu relies on the MAP sensor during open loop operations (WOT).
