DsmChips?

[DsmWhiplash]

I just recently discovered this dsmchips.com website. They modify your ecu like tmo does. But there so much cheaper than tmo but do the same thing. Do any of you have them? any feedback would be appreciated. Thank you for your time.

 

[SpoOLxExO]

Yeah, they work the same, a couple of my buddies have em.
You are correct, they are just TMO rip-off programs. Alot of companies are doing it now, especially on ebay. Either way TMO isnt doing it anymore. I don't know if they did it because people are ripping it off, or because they got sick of modding ECU's, who knows.

P.s. Hows that GSX coming? It looks like Maine isn't so far from having a solid DSM scene!

Incorrect they have a lot of different features available that the TMO does not. Most notably correction for larger injectors.

I have one for the rally car w/ the data logger cable installed........

These are NOT TMO ripoff chips, they are all Jeff's own code.

I'd suggest them.

I will be getting one made for my 90 very soon.
The fact that I can get the IPW compesated for my injector size is a huge plus...

he is a great guy and makes a great product

I have one of Jeff’s chips and it is great. The car is easier to drive around town with the injector comp. The injector comp was not as close as I hoped it would be, but I am starting to think that it is because the injectors flow more then they are rated for. Jeff is a great guy and very fast respond to emails and to burn and ship the chips.

A++ vendor in my list

I would say if you're a 1G guy, go for the www.dsmchips.com stuff ( which is very worthwhile ), and for 2G guys, use the DSMlink. I wish they had the dsmchips for the 2Gs though. Even though the DSMlink is awesome, 90$ for a chip that does all that makes me green with envy.



Should've kept the 1G, but I do love my 2G so.

OH but he does

Im currently testing his chip.

My hacks::::

7600rev / 5500stutter / 6000 3step
650 correction
MAS hacks
850 idle
knock guage (testing this today)

Keep us updated! Saving money is almost more important than going fast for me.

Would you need a 95 EPROM ECU to make it work, or could any ECU be socketted for it?

 

[biglipps66]

Need a 95 EPROM for it to work..

Here is the only phone pic I have of the EPROM i used and a socket.

Ive gone through MANY chips with MANY different things.

Good info. Thanks!

 

[biglipps66]

went ahead an made an official post in the tuning section

My dsmchips on the way. Jeff O is a great man and very fast respond to emails.

Hello! Another satisfied DSMChip owner here.

In addition to the usual upgrades I also had Jeff fix the ignition timing at WOT for me so they're not linked to the airflow tables. Now I can add and subtract fuel using the AFC and it won't affect the timing maps. I even upgraded to 720cc injectors and the timing stays the same. It's so nice having one less variale. I don't feel like I'm playing 3D chess when I tune anymore. Knock will still pull timing, so it's safe.

Errr.. do you have any information about how this was done? With the way the timing maps work in the ECU, I can't figure out how this would be possible.

Second of all, why would you want it? It's VERY unlikely that you know what tming is optimal for your car, especially since that changes day to day. While having to change it through airflow changes is not the best way, it's better than not being able to change it at all.

 

[pneumo]

I agree that having the timing fixed at a certain level during WOT runs may not be optimal, but it's much better than having the timing fall above 6k rpm.

I'm not exactly sure how the timing stays where it is (20 degrees) despite changing from 550 injectors and 19 psi (high airflow) to 720 injectors and 14 psi boost ( low airflow), but it does. I havent seen a breakdown of the timing maps or any of the code, but the best I can figure is the top two or three timing maps are all the same, so no matter what is done with the airflow at WOT the timing doesn't change. Please forgive me if this isn't how timing works. I'm just trying to make sense of what I see in my logs.

BTW what I see on a log with no knock is the timing starts at 15 degrees @4k rpm, slowly advances to 20 degrees by 5.5k rpm and it holds 20 till redline at 8k.

This has changed the feel of the car dramatically. I really wish I had a dyno chart to see what the powerband does, because before the chip I could feel the power drop off if I tried to go above 6500 rpm. Now the motor pulls up to 7500 rpm easily. I know that's not proof, but if you drove my car before and after the chip you could tell the difference in high rpm power.

Ok! It seems that there are some excellent features included in keydiver chips that are not included in the TMO program, but since its just a reprogram of the original Mitsu code, I used deductive reasoning in my statement.

Big ups to keydiver though in continuing the tradition of "Unlocking" the very stubborn DSM ECU, for a more than decent price!!! Should be one of the first mods in addition to a boost guage and a filter IMO.

If you are flowing more than X amount of air, you stay on the top airflow/rev line of the table for timing and fuel. With a decent sized turbo, you will hit this point at 15 PSI, give or take a little. Then no matter how much more airflow you have above that, timing will not be affected. It will change with RPM still. But if you use an AFC to add or subtract a few % of airflow signal, you will still be above that level. Now if you subtracted a big % from the airflow, it might be enough to cause you to drop back to lower lines in the timing and fuel tables, and get more timing.

Is this the same for 2G and 1G ECUs? Maybe a dumb question, but does adding fuel affect how the ECU decides what timing is good? Example: You subtract a certain % and the ECU adds a little extra timing. If you add fuel, will it decrease the timing? Dumb question.

 

[kpt4321]

Yes, 1g and 2g ECU's do the same thing in that regard.

Changing the A/F ratio does not effect timing. However, what does effect timing is the airflow signal seen by the ECU, which is what a SAFC modifies.

 

[Lof8]

would one of these chips allow me to run a 2g mas and bigger injectors in my 1g without using an AFC? I'm interested in making useful power in a daily driver. I haven't used an AFC before and dont want to be constantly tinkering with it to make the absolute maximum power. I just want a good daily driver setup and am content running below the components' max abilities. If these chips will allow me to do that, then I am very interested.
thanks, Andy

I want a chip, but I wish DSM chips had a selectable turbo gauge. I like the idea of seen duty cycle. I also wish they had the security the TMO chip had. I also liked how you could change the shift points ect. with DSM chips you are stuck with what you ordered. I did not even know TMO was around till they were out of of the game. Guess I will be getting a DSMchip
