ok so have developed an issue lately. Started out with a lean spot in the tune around 4400rpms. I basically just tuned it out by targeting a richer AFR in the DA table. Now, when I left the track wed my fuel pressure was lower than normal. Around 36psi with the vacuum live on so prob around...

So I'm finishing up tuning my setup and just noticed that the engine displacement on the speed density tab is wrong. it's 2.7L. I have no idea how it got like that. Maybe during firmware update or something? IDK. Question is, if i change it back to 2.0 is it going to affect the tune or is that...

Ok, so I'm not new to DSMs, big turbo cars nor drag racing..... With that being said, I'm having trouble building boost at the line and my 60' sucks on this setup. My profile is updated and all mods on there. I'll attach a log of the last pass I made at test and tune. 7.99@94 1.96 60' in...

Think I'm getting there with the tune. Would just like others to weigh in. I see that my boost est is still off a little up top from my MAP. I reduced VE some there to try to get it in check but it didn't lower much so I did another boost leak test this morning. My compressor sucks but I...

I'm posting this for a buddy that doesn't really use forums or even the internet really. Car is a 98 GSX with a built 2.3L 7 bolt. Super 94 turbo on e85 and all supporting mods. It would take all day to list the mods on the car. Car was fully tuned recently and running perfectly. He drove...

bigdnno98 submitted a new DSM Profile :My 2GRead more about this vehicle here...

Ok so I'm pretty sure I have a couple of non-related issues. First, my old school FP Green is spooling very slowly for what it is. I'm guessing 700-800 RPMs slower than it should. I've boost leak tested this car numerous times. Last 2 in a row have came back with 0 boost leaks. I'm thinking...

I'm getting frustrated with this car. The car came with a greddy profec b the original one. I'm not sure if it ever worked. When I got the car I pulled out the whole interior including the boost controller and cleaned it all up and put it back together. With the EBC hooked up I was spiking to...

I have a 6 bolt swapped 99 GSX I bought a couple of months ago. I drove it 45 minutes home when I bought it. It ran pretty decent. I did a couple mods once I got it home including upgrading from link 2.5 to v3, SD conversion and new FIC1120 injectors. The car now is sparatically blowing the 30A...

I'm trying to setup my SD tune. I'm having a hard time and I think it's because the MAP value dsm link is logging isn't near what the mechanical boost gauge is reading. I have an ecmtuning sd cable. I cut the gm map connector off and wired it into my AEM 3.5 bar. I started the car with my new v3...

So a little about myself. I'm 36 and have been building cars since I was 18. Started with an S14 240sx SC KA build, then SR20 swap. Had that car for a long time and a bunch of different setups. Best 1/4 was 13.3. I forget the trap. I bought a brand new GST in 1998. I really loved that car. I...
